Answer:

76  14/20

(76  7/10) simplified

Step-by-step 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
