Question

How do you evaluate `24 11/16 + 42 9/16`?

Answer 1

`67 1/4`

Explanation:

As the fractions have the same denominator we do not need to change much. Why not split the calculation into 2 parts.

Part 1 for the whole numbers.
Part 2 for the fraction number parts

So we have `(24+42)+(11+9)/16`

Giving `66+ 20/16" " ->" " 66+1 + 4/16`

But `4/16 = (4-:4)/(16-:4) = 1/4` giving

`67 1/4`
