Introduction

Mathematics is an essential part of our daily lives, and it's used in various aspects, from simple calculations to complex problem-solving. In this article, we will explore a real-world math problem that involves calculating the cost of a certain number of pears. We will use this problem to demonstrate how to apply mathematical concepts to solve everyday problems.

The Problem

We are given that 15 pears cost R5.60. We need to find out how much 27 of the same pears will cost.

Step 1: Understand the Problem

To solve this problem, we need to understand the given information and what is being asked. We are given the cost of 15 pears, and we need to find the cost of 27 pears. This is a simple ratio problem, where we need to find the cost of a certain number of pears based on the given cost of a smaller number of pears.

Step 2: Identify the Ratio

The given information is that 15 pears cost R5.60. This means that the ratio of the number of pears to the cost is 15:5.60. We can simplify this ratio by dividing both numbers by their greatest common divisor, which is 5. This gives us a simplified ratio of 3:1.12.

Step 3: Apply the Ratio

Now that we have the simplified ratio, we can use it to find the cost of 27 pears. We know that 3 pears cost R1.12, so we can multiply this cost by 9 to find the cost of 27 pears. This gives us a cost of R10.08.

Step 4: Check the Answer

To check our answer, we can multiply the cost of 15 pears by 1.8 to find the cost of 27 pears. This gives us a cost of R10.08, which matches our previous answer.

Conclusion

In this article, we used a real-world math problem to demonstrate how to apply mathematical concepts to solve everyday problems. We started by understanding the problem and identifying the ratio of the number of pears to the cost. We then applied the ratio to find the cost of 27 pears and checked our answer to ensure that it was correct.
