a_sh-v [17]

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
