Answer :
To decrease R 3700 in the ratio of 2:5, you can follow these steps:
1. Understand the Ratio:
The ratio 2:5 means we are dividing the amount into two parts, where the first part is represented by 2 and the second part by 5. The total of the parts is 2 + 5 = 7.
2. Calculate the Decrease Amount:
You will decrease R 3700 by the first part of the ratio. To find this decrease amount, multiply the total amount by the fraction represented by the first part of the ratio:
[tex]\[
\text{Decrease Amount} = \frac{2}{7} \times 3700
\][/tex]
3. Perform the Calculation:
[tex]\[
\text{Decrease Amount} = \frac{2}{7} \times 3700 = 1057.14
\][/tex]
So, you will decrease R 3700 by R 1057.14.
4. Calculate the Decreased Amount:
Subtract the decrease amount from the original amount to find the new amount:
[tex]\[
\text{Decreased Amount} = 3700 - 1057.14 = 2642.86
\][/tex]
Therefore, when R 3700 is decreased in the ratio of 2:5, the decrease amount is approximately R 1057.14, and the remaining amount is approximately R 2642.86.
