The whole race is 12 3/4 kilometers.
The correct equations that represent this question are:
(8 1/2) ÷ 2/3 = ?
2/3 × ? = 8 1/2
(8 1/2) × 3/2 = ?
In this question we have been given Diego has run 2/3 of a race""s distance. He has run 8 1/2 kilometers.
We need to find the length of the whole race.
Let the whole race be x.
Since Diego has run 2/3 of a race's distance which is 8 1/2 kilometers. The length of the whole race will be given by an equation:
2/3 × x = 8 1/2
x = (8 1/2) ÷ 2/3
x = (8 1/2) × 3/2
x = 17/2 × 3/2
x = 51/4
x = 12 3/4 kilometers.
Therefore, the length of the whole race= 12 3/4 kilometers.
