Answer:

24

Explanation:

You want the mixed-number sum 1 1/4 +2 1/3 +3 2/3 +4 1⁄2 +5 1/2 +6 3/4.

Sum

It is convenient to group the numbers that have the same denominators.

= (1 1/4 +6 3/4) +(2 1/3 +3 2/3) +(4 1/2 +5 1/2)

We notice that the fractional parts in each group add to 1, so the sum is ...

= 8 +6 +10

= 24
