Question

A piece of string 85 cm is divided into three pieces in the ratio 2 : 3: 5. Calculate: i) shortest piece

Answer 1

Answer: 17 cm

Explanation:

First step is to add up the numbers in the ratio:

= 2 + 3 + 5

= 10

The shortest piece according to the ratio is the 2 in the ratio. To find out the length this 2 corresponds with, use two as the numerator and 10 as the denominator:

= 2 / 10 * 85 cm

= 17 cm
