The amount each boy receives from the R2100 is R420, R700 and R980 respectively

How to find ratio

Total amount = R2100

Ratio = 3 : 5 : 7

Total ratio = 3 + 5 + 7

= 15

First boy = 3/15 × 2100

= 0.2 × 2100

= R420

Second boy = 5/15 × 2100

= 0.33333333333333 × 2100

= R700

Third boy = 7/15 × 2100

= 0.46666666666666 × 2100

= R980
