Answer:

5/12

Step-by-step explanation:

convert 1/3 to 4/12 and 1/4 to 3/12 so 3+4=7 so 7/12 dropped out so now 12-7=5 so 5/12 is the answer

The answer is 42.

Since 1/3 of them dropped out, 2/3 are still in the race. 2/3 of 84 is 56.

For the second part, 1/4 of them dropped out, meaning 3/4 of the REMAINING runners are still in. 3/4 of 56 is 42.
