Orchard Land Allocation Problem Apples, Lemons, And Tree Tomatoes

This article delves into a practical mathematical problem concerning land allocation in an orchard. We will explore how a farmer divides their land among different types of fruit trees, specifically apples, lemons, and tree tomatoes. This exercise not only reinforces fundamental arithmetic skills but also highlights the application of fractions in real-world scenarios.

Understanding the Problem: Keywords

Before diving into the solution, let's break down the core elements of the problem. The farmer owns a total of 2 3/4 hectares of orchard land. This is our initial value, representing the whole area. A portion of this land, 1 1/4 hectares, is dedicated to apple trees. The remaining land is then further divided. One-fourth of the remaining land is used for lemon trees, and the rest is allocated to tree tomatoes. The central question we aim to answer is: What fraction of the total land is occupied by tree tomatoes?

Step-by-Step Solution: A Detailed Approach

To solve this problem effectively, we will follow a step-by-step approach, converting mixed fractions to improper fractions, performing subtraction and multiplication, and ultimately arriving at the fraction of land occupied by tree tomatoes. This methodical approach not only provides the solution but also enhances understanding of the underlying mathematical principles.

1. Converting Mixed Fractions to Improper Fractions

The initial step involves converting the mixed fractions into improper fractions. This simplifies the subsequent calculations. Let's start with the total land area: 2 3/4 hectares. To convert this to an improper fraction, we multiply the whole number (2) by the denominator (4) and add the numerator (3), then place the result over the original denominator. So, (2 * 4) + 3 = 11. Therefore, 2 3/4 is equivalent to 11/4 hectares.

Next, we convert the area occupied by apple trees, 1 1/4 hectares, into an improper fraction. Similarly, (1 * 4) + 1 = 5. Thus, 1 1/4 is equivalent to 5/4 hectares.

2. Calculating the Remaining Land After Allocating for Apples

Now, we need to determine the amount of land remaining after allocating space for apple trees. This involves subtracting the area occupied by apples (5/4 hectares) from the total land area (11/4 hectares). The calculation is straightforward since the fractions have the same denominator: 11/4 - 5/4 = 6/4 hectares. This means that 6/4 hectares of land remain after allocating space for apples. We can simplify this fraction to 3/2 hectares.

3. Determining the Land Occupied by Lemon Trees

The problem states that one-fourth of the remaining land is occupied by lemon trees. To find this amount, we need to multiply the remaining land area (6/4 hectares or 3/2 hectares) by 1/4. So, (6/4) * (1/4) = 6/16. This fraction can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 2. Therefore, 6/16 simplifies to 3/8 hectares. Alternatively, using the simplified remaining land (3/2), we calculate (3/2) * (1/4) = 3/8 hectares. This confirms that 3/8 hectares of land is occupied by lemon trees.

4. Calculating the Land Occupied by Tree Tomatoes

The final step is to determine the fraction of land occupied by tree tomatoes. We know that the remaining land after allocating for apples is 6/4 hectares (or 3/2 hectares). We also know that 3/8 hectares of this remaining land is occupied by lemon trees. Therefore, to find the land occupied by tree tomatoes, we subtract the land occupied by lemons (3/8 hectares) from the remaining land (6/4 hectares). To do this, we need a common denominator. Converting 6/4 to have a denominator of 8, we multiply both the numerator and denominator by 2, resulting in 12/8. Now we can subtract: 12/8 - 3/8 = 9/8 hectares. This means that 9/8 hectares of land is occupied by tree tomatoes.

5. Expressing the Answer as a Fraction of the Total Land

Finally, to express the land occupied by tree tomatoes as a fraction of the total land, we divide the area occupied by tree tomatoes (9/8 hectares) by the total land area (11/4 hectares). Dividing fractions is the same as multiplying by the reciprocal of the divisor. The reciprocal of 11/4 is 4/11. So, (9/8) / (11/4) is the same as (9/8) * (4/11). Multiplying these fractions, we get (9 * 4) / (8 * 11) = 36/88. We can simplify this fraction by dividing both the numerator and denominator by their greatest common divisor, which is 4. Therefore, 36/88 simplifies to 9/22. This means that tree tomatoes occupy 9/22 of the total land.

Detailed Explanation of Each Step

Let's delve deeper into each step of the solution to ensure a comprehensive understanding of the underlying mathematical concepts.

Converting Mixed Fractions: A Foundation for Calculation

Converting mixed fractions to improper fractions is a crucial first step in solving many mathematical problems involving fractions. A mixed fraction combines a whole number and a proper fraction (where the numerator is less than the denominator). An improper fraction, on the other hand, has a numerator that is greater than or equal to the denominator. Converting to improper fractions simplifies arithmetic operations such as addition, subtraction, multiplication, and division.

In our problem, we converted 2 3/4 to 11/4. This process involves multiplying the whole number (2) by the denominator (4), which gives us 8. We then add the numerator (3), resulting in 11. This becomes the new numerator, while the denominator remains the same (4). Thus, 2 3/4 becomes 11/4. Similarly, 1 1/4 is converted to 5/4.

Understanding this conversion is fundamental for working with fractions and ensuring accurate calculations throughout the problem-solving process.

Calculating Remaining Land: Subtraction of Fractions

After converting the mixed fractions to improper fractions, the next step involves finding the remaining land after allocating space for apple trees. This requires subtracting the area occupied by apples (5/4 hectares) from the total land area (11/4 hectares). When subtracting fractions with the same denominator, we simply subtract the numerators and keep the denominator the same. In this case, 11/4 - 5/4 = (11 - 5)/4 = 6/4 hectares.

The resulting fraction, 6/4, can be simplified by dividing both the numerator and the denominator by their greatest common divisor, which is 2. This gives us 3/2 hectares. This simplification makes the subsequent calculations easier to manage.

This step highlights the importance of understanding fraction subtraction, a core concept in arithmetic and essential for solving real-world problems involving division and allocation.

Determining Land for Lemon Trees: Multiplication of Fractions

The next part of the problem involves calculating the land occupied by lemon trees, which is one-fourth of the remaining land. To find this, we multiply the remaining land area (6/4 hectares or 3/2 hectares) by 1/4. When multiplying fractions, we multiply the numerators together and the denominators together. So, (6/4) * (1/4) = (6 * 1) / (4 * 4) = 6/16. Alternatively, (3/2) * (1/4) = (3 * 1) / (2 * 4) = 3/8. Both approaches should lead to the same result after simplification.

The fraction 6/16 can be simplified by dividing both the numerator and the denominator by their greatest common divisor, which is 2. This gives us 3/8 hectares. This calculation demonstrates the application of fraction multiplication, a key skill in determining proportions and parts of a whole.

Calculating Land for Tree Tomatoes: Subtraction and Simplification

To find the land occupied by tree tomatoes, we need to subtract the land occupied by lemon trees (3/8 hectares) from the remaining land after allocating for apples (6/4 hectares). However, before we can subtract, the fractions must have a common denominator. We convert 6/4 to have a denominator of 8 by multiplying both the numerator and the denominator by 2, resulting in 12/8. Now we can subtract: 12/8 - 3/8 = (12 - 3)/8 = 9/8 hectares.

This step involves both subtraction of fractions and the concept of finding a common denominator, which is crucial for performing addition and subtraction with fractions. The result, 9/8 hectares, represents the area occupied by tree tomatoes.

Expressing the Final Answer: Division and Simplification

The final step is to express the land occupied by tree tomatoes as a fraction of the total land area. This involves dividing the area occupied by tree tomatoes (9/8 hectares) by the total land area (11/4 hectares). Dividing fractions is equivalent to multiplying by the reciprocal of the divisor. The reciprocal of 11/4 is 4/11. So, (9/8) / (11/4) is the same as (9/8) * (4/11).

Multiplying these fractions, we get (9 * 4) / (8 * 11) = 36/88. This fraction can be simplified by dividing both the numerator and the denominator by their greatest common divisor, which is 4. Therefore, 36/88 simplifies to 9/22. This final fraction, 9/22, represents the proportion of the total land occupied by tree tomatoes.

This step underscores the importance of understanding fraction division and simplification in presenting the final answer in its simplest form.
