Question

52 4/9 plus 8 7/8 equals?

Answer 1

The answer would be 61 23/72

Answer 2

First you need to find a common denominator, I'll use 72 so then it becomes:
52 32/72 + 8 63/72
Then I make them improper fractions so it becomes:
3776/72+639/72
Add them together and you have:
4415/72, this can be made into a mixed number:
61 23/72

Hope this helps :)
