Question

How many pieces of string each measuring 10cm can be cut from a length measuring 2.5metres​

Answer 1

Answer is 25 pieces of string

Step by step

First we will change the full length from meter to cm to match the cut size

2.5 multiply the full length value by 100
= 250 cm

Now divide the full length of 250 cm by 20 cm cut pieces

250 cm ÷ 10 cm = 25 pieces
