The answer would be Find 40% of 20 because you would round 43% down and 18 up. Hope this helps :) 

Answer:

Find 40% of 20.

Step-by-step explanation:

The length of the race = 18 mile

The runner has run 43% of the race.

Total length completed by the runner = 43/100 * 18 = 7.74 miles

Among the given options:

1) 40% of 10 = 40/100 * 10 = 4

2) 40% of 20 = 40/100 * 20 = 8

3) 50% of 10 = 50/100 * 10 = 5

4) 50% of 20 = 50/100 * 20 = 10

The closest value with respect to the distance completed by the runner (7.74) from among the given options is the second one,namely,

Find 40% of 20.
