Answer 2

Answer:

One-eighth of an hour

Explanation:

Given that Carrington used 3/4 of the 1/2 of an hour allotted for an exam to do the first 3 problems.

We are to calculate the time that he has left for the remaining part of the exam.

We have

Total time used i the first three problems is given by

$\frac{3}{4}$×$\frac{1}{2}$= $\frac{3}{8}$

Therefore, the time left to complete the remaining part of the exam will be

Tr= $\frac{1}{2}$ - $\frac{3}{8}$= $\frac{4-3}{8}$=$\frac{1}{8}$ hour
