Question

20 9\16 + 24 5\8 + 21 5\16 + 23 3\8 DON'T SIMPLIFY

Answer 1

88 14/16

Explanation:

I call these mixed numbers, a mixed number is written as a b/c and it means

`a+(b)/(c)`

So, we can use the above to re arrange our expression to a more convenient presentation.

we have>

`20+(9)/(16) + 24+(5)/(8) + 21+(5)/(16)+23+(3)/(8)\\  \\88+(14)/(16) +(8)/(8) \\\\89+(14)/(16)`

88 14/16, we tend to no simplify this expression anymore since, the number 14/16 usually means something in real life, like the diameter for a construction pipe
