42 students ran in a race. a third of them dropped out in the first half of the race. only a fourth of the remaining runners actually did complete the race. how many students finished the race? (check work required)

The number of the students that remained in the race after the first half is calculated by multiplying the number of students by 2/3 because 1/3 of them dropped out.

                         N (first half) = 42 x 2/3

                         N (first half) = 28

Then, the number of students who finished the race is one-fourth of the calculated number above. Thus, the final answer to this item would be 14.

25% is the answer
