Question

A tank has 82 3/4 litres of water, 24 4/5 litres were used, and the tank was filled with another 18 3/4 litres. What is the final volume of the water in the tank?

Answer 1

76 14/20

(76 7/10) simplified

Explanation:

First we make the denominator of the fraction equal

82 15/20

24 16/20

18 15/20

We then subtract

82 15/20 - 24 16/20

81 35/20 - 24 16/20 =

57 19/20

Then we add

57 19/20 + 18 15/20=

76 14/20

(76 7/10) simplified
