Question

Can anyone help me with this problem?

Answer 1

a1

Explanation:

Just add the numerators if both fractions to get: a + 1 = a1

Answer 2

a+1

Explanation:

Well if you have the same denominator, which in this case you do, it's equal to b, you can simply add the numerators. This gives you the expression
`(a+1)/(b)` so the numerator is a+1
