Mark had 24 newspapers to deliver. In one apartment building, he delivers 3/8 of them. In the next apartment building, he delivers 2/3 of the remaining amount. How many papers does he have left to deliver?

Answer 1

In the first apartment, Mark delivers 24 * (3/8) = <<24*(3/8)=9>>9 newspapers.
He has 24 - 9 = <<24-9=15>>15 newspapers left.
Then he delivers 15 * (2/3) = <<15*(2/3)=10>>10 newspapers in the next apartment building.
So, Mark has 15 - 10 = <<15-10=5>>5 newspapers left to deliver. Answer: \boxed{5}.
