Question

In 2\3 of an hour, the workers had installed 2/5 of the flooring. At that rate, what fraction of the flooring is finished after 1 hour

Answer 1

Answer:

3/5

Explanation:

In 2/3 of an hour, the fraction of flooring installed = 2/5

Therefore:

$\begin{gathered} In\text{ 1 hour, the fraction of flooring installed} \\ =\frac{2}{5}\div\frac{2}{3} \\ =\frac{2}{5}\times\frac{3}{2} \\ =\frac{3}{5} \end{gathered}$

3/5 of the flooring is finished in 1 hour.
