Question

A piece of rope is cut into three lengths in the ratio 7:2:5 if the smallest length is 1.48m find the length of the longest piece of rope and the length of the original rope

Answer 1

5.18, 10.36

Explanation:

the smallest one is 2 parts

1.48/2 so each part is 0.74m

the longest piece of rope is 7 parts

0.74*7=5.18m

the rope total is 14 parts (7+2+5)

14*0.74=10.36m
