Question

a rope of length 300m is cut into three pieces 3:5:7 .Find the length of each piece of rope.​

Answer 1

Step-by-step explanation:

Let each length be,

3x, 5x and 7x

Accoding to the question,

3x + 5x +7x = 300

: 15x = 300

: x = 300/15

= 20

HENCE,

1st length = 3 × 20 m

= 60m

2nd length = 5 × 20m

= 100m

3rd length = 7 × 20m

= 140m

So,here is your answer.
