Answer 1

Answer:

5m=500cm

2m85cm=285cm

then remaining piece is (500-285)=215cm

thus 2m 15cm is remaining

Answer 2

A cloth is 5m long.

Cloth needed is 2m 85cm.

First we covert m to cm

We know that 1m=100cm.

Then,

$5 \times 100 = 500cm$

and

$2 \times 100 + 85 = 285cm$

remainig piece is

$500 - 285 = 215cm = 2.15m$
