(It's 23 1/2)
You could do one of two things:
- You could work on the components separately; that is, first add 12 and 10 ( = 22 ), then add 3/4 to 3/4 ( = 1 ½ ). You then add these two together: 22 + 1 ½ = 23 ½.
- You could convert them all to improper fractions: 12 becomes 48/4 (multiply by 4), and to this we add the 3/4, giving 51/4; likewise, 10 becomes 40/4 and 10 3/4 is 43/4. We add these together:
51/4 + 43/4 = 94/4.
We then simplify, perhaps by doing the division:
94 / 4 = 23.5 = 23½.
