Question

A pool is 6/7 full of water. If 1/6 of the water leaks out, how full will the pool be?

Answer 1

All written in simplest form...
How full the pool will be:

As a fraction - 29/42
As a decimal - 0.690472
As a percentage - 69.05%

Answer 2

Subtract 1/6 from 6/7

First rewrite the fractions to have a common denominator:

6/7 = 36/42

1/6= 7/42

Now you have 36/42 - 7/42 = 29/42

The pool is 29/42 full
