Question

A wire of length 96 cm is cut into three pieces in the ratio 2:3:7. Find the lengths of each piece.

Answer 1

Answer:

(1)16m. (2)24m (3) 56m

Explanation:

the sum of ratio=2+3+7=12

first piece= 96×2/12=16m

second piece=96×3/12=24m

third piece=96×7/12=56m

Answer 2

Answer:

Explanation: let the length be x

2x+3x+7x=96

12x=96

x=96/12

x=8

So the previous length was=2x+3x7x

So 2x=2×8=16

3x=3×8=24

7x=7×8=56

Checking answer

16+24+56=96
