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
