Find the sum 41/2+21/2 write the sum as a mixed number so the fractional part is less than 1

 31

note: there is no fractional part, so the fractional part is essentially 0. The answer is a whole number

Explanation:

To get this answer, you first add the fractions. Add only the numerators while keeping the denominator 2 the same. So we have 41+21 = 62 as the new numerator and that is over 2

Therefore, 41/2 + 21/2 = (41+21)/2 = 62/2

From here, we divide 62 in half to get 31. The denominator 2 cancels out and goes away when we divide it by 2

This means we go from 62/2 to 31 which is the final answer. This is not a mixed number as there is no fractional part. Instead, it is a whole number.

I guess if you wanted, you can write 31 as 31 & 0/2, though that seems like unneeded extra work in my opinion.
