Word problem Involving fractions and division A road crew must repave a road that is \( \frac{4}{5} \) miles long. They can repave \( \frac{1}{20} \) miles each hour. How long will it take the crew to repave the road? Write your answer in simplest form.

To find out how long it will take the crew to repave the road, we need to divide the total length of the road, \( \frac{4}{5} \) miles, by the rate at which they can repave, \( \frac{1}{20} \) miles per hour. So we perform the division: \[ \frac{4}{5} \div \frac{1}{20} = \frac{4}{5} \times \frac{20}{1} = \frac{4 \times 20}{5 \times 1} = \frac{80}{5} = 16 \] Thus, it will take the crew 16 hours to repave the road. The simplest form of this answer is 16.
