Introduction

In mathematics, dividing a quantity in a given ratio is a common problem that requires a clear understanding of the concept of ratios and proportions. The problem of dividing $R 5600$ in the ratio $4: 5: 7$ is a classic example of this concept. In this article, we will explore the steps involved in dividing a quantity in a given ratio and apply this concept to the specific problem of dividing $R 5600$ in the ratio $4: 5: 7$ .

Understanding Ratios

A ratio is a way of comparing two or more numbers by division. It is usually expressed as a fraction or a colon (:). For example, the ratio $4: 5$ can be expressed as the fraction $\frac{4}{5}$ or as $4: 5$ . Ratios can be used to compare quantities, such as the number of boys to girls in a class, or the number of apples to oranges in a basket.

Dividing a Quantity in a Given Ratio

To divide a quantity in a given ratio, we need to follow these steps:

Add up the parts of the ratio: The first step is to add up the parts of the ratio. In this case, the ratio is $4: 5: 7$ , so we add up the parts: $4 + 5 + 7 = 16$ .
Find the value of each part: Once we have added up the parts of the ratio, we need to find the value of each part. To do this, we divide the total quantity by the sum of the parts of the ratio. In this case, the total quantity is $R 5600$ and the sum of the parts of the ratio is $16$ , so we divide $5600$ by $16$ to get the value of each part: $5600 ÷ 16 = R 350$ .
Multiply the value of each part by the corresponding part of the ratio: Once we have found the value of each part, we need to multiply it by the corresponding part of the ratio. In this case, the value of each part is $R 350$ and the ratio is $4: 5: 7$ , so we multiply $350$ by $4$ to get the first part: $350 × 4 = R 1400$ , by $5$ to get the second part: $350 × 5 = R 1750$ , and by $7$ to get the third part: $350 × 7 = R 2450$ .

Applying the Concept to the Problem

Now that we have understood the concept of dividing a quantity in a given ratio, we can apply it to the specific problem of dividing $R 5600$ in the ratio $4: 5: 7$ . We have already followed the steps outlined above to find the value of each part: $R 1400$ , $R 1750$ , and $R 2450$ . Therefore, the final answer to the problem is:

The first part of the ratio is $R 1400$ .
The second part of the ratio is $R 1750$ .
The third part of the ratio is $R 2450$ .

Conclusion

In conclusion, dividing a quantity in a given ratio is a common problem that requires a clear understanding of the concept of ratios and proportions. By following the steps outlined above, we can easily divide a quantity in a given ratio. In this article, we have applied this concept to the specific problem of dividing $R 5600$ in the ratio $4: 5: 7$ and found the value of each part: $R 1400$ , $R 1750$ , and $R 2450$ . We hope that this article has provided a clear understanding of the concept of dividing a quantity in a given ratio and has helped readers to apply this concept to their own problems.
