9 1/2+ 1 1/2=?
We have to check if their denominators, or bottom numbers, are the same.
Both of their denominators are 2, so all we have to do it add!
First, we'll add the whole numbers, which are 9 and 1.
9+1=10 so the whole number is 10.
Then we'll add the numerators, or top numbers, together.
1+1=2 so the numerator is 2.
We don't add the denominators though, because the denominator ALWAYS stays the same.
So your answer is going to be 10 2/2=11

First, you want to make them into irregular fractions.

Separate them into two parts:

Part one: 9 1/2; Part two: 1 1/2

Part one:
9 x 2 = 18, 18 + 1 = 19, so 9 1/2 = 19/2

Part two:
1 x 2 = 2, 2 + 1 = 3, so 1 1/2 = 3/2

Then add part one and part two:

19/2 + 3/2 = 22/2

Then divide 22 by 2 to get the answer

22 / 2 = 11.
