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
