A roll of cloth is 15 metres long. Three quarters of the cloth is used. How much is left?

If a roll of cloth is 15 metres long and three quarters of the cloth is used, and you would like to know how much is left, you can calculate this using the following steps:

three quarters of 15 metres = 3/4 * 15 metres = 45/4 metres = 11.25 metres is used

15 metres - 11.25 metres = 3.75 metres is left

The result is 3.75 metres or 3 3/4 metres.

Four quarters = 15

One quarter = 15/4 = 3,75

Three quarters = 3,75*3 = 11,25

15-11,25 = 3,75 metres left
