Question

One class collects 8 1/4 pounds of recyclable materials. Another class collects 1 1/2 times as many pounds as the first class. How many pounds of recyclable materials do the two classes collect altogether?

Answer 1

It should be 20.625

Example:
8 1/4 x 1 1/2 and that is 12.375 then you add 8 1/4 and that should be 20.625

8 1/4 = 8.25 pounds

1 1/2 of 8.25 = 12.375 pounds
