Question

Sean paints 8/15 of a fence in 1 hour. He paints 3/10 of the fence less in the second hour. What fraction of the fence did he paint in two hours? Did he finish the job in two hours?

Answer 1

Answer: $\frac{3}{10}$

Step-by-step explanation:

Given

Sean paints $\frac{8}{15}$ of a fence in 1 hour

Sean paints $\frac{3}{10}$ part less in the second hour

So, fraction he paints in the second hour = $\frac{8}{15}-\frac{3}{10}=\frac{16-9}{30}=\frac{7}{30}$

Paint in 2 hours = $\frac{8}{15}+\frac{7}{30}=\frac{16-7}{30}=\frac{9}{30}$

                          =$\frac{3}{10}$

No, he did not finish his job
