Still a little vague. As written you could mean:



or


or what Stapel_eliz wrote or three or four other possibilities (English is tricky, ain't it?).

So, use grouping symbols like parentheses: "3 is over (a squared + a)" and such. Help us see what the entire numerators and denominators are.

The answer is as listed if a particular one of the earlier guesses as to meaning was correct. If that particular guess was incorrect, then "the answer" is something else.

Unfortunately, we'll never know for sure until the original poster provides the necessary clarification....
