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?

Sean didn't finish the job. He painted 23/30 of the fence in two hours.

Step-by-step explanation

He didn't finish the job because 23/30 is not finished. It isn't finished because Sean is less than 23/30 of the way done. That doesn't seem done to me.

I got the fraction 23/30 by looking at the problem carefully. He painted 3/10 of the fence "less" than the first hour which was 8/15 of the fence. So that means we have to subtract 8/15 and 3/10 to get 7/30.

Now, we just figured out how much Sean painted in the second hour, and the question is asking what fraction of the fence did he paint in BOTH hours. Meaning we have to add the first and second hour to get the answer of 23/30.
