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?

Respuesta :

Answer: [tex]\frac{3}{10}[/tex]

Step-by-step explanation:

Given

Sean paints [tex]\frac{8}{15}[/tex] of a fence in 1 hour

Sean paints [tex]\frac{3}{10}[/tex] part less in the second hour

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

Paint in 2 hours = [tex]\frac{8}{15}+\frac{7}{30}=\frac{16-7}{30}=\frac{9}{30}[/tex]

                          =[tex]\frac{3}{10}[/tex]

No, he did not finish his job
