Answer 2

Your answer:-

65 m

Simple Verification:-

Length of the pipe = 2.5 m

Pieces cut = 60 cm, 35 cm, 90 cm

We can take pipe left as X

So Pipe Left = X

1.- Convert the length of the original pipe to cm

100 cm ----------------- 1 m                                                                                           x      ------------------2.5 m

 x = (2.5 x 100) / 1

 x = 250 cm

250 cm - 60 cm - 90 cm - 35 cm

250 cm - 185 cm

65 cm
