Question

A rope to length 30m is divided in the ratio 2:3. calculate the length of the longest

Answer 1

30 : (2 + 3) *3 =

6 * 3 =

18 cm (your answer)

Answer 2

longest part = 18 m

add the parts of the ratio 2 + 3 = 5

divide 30 by 5 to find the value of 1 part of the ratio

`(30)/(5)` = 6 ← 1 part

2 parts = 2 × 6 = 12 m

3 parts = 3 × 6 = 18 m ← longest part
