Question

For every 3 packages that Marcella wraps she uses 1/2 of a roll of wrapping paper if she uses 2 1/2 rolls of wrapping paper how many packages has she wrapped

Answer 1

She wrapped 5 packages

Answer 2

Answer:

The answer is 15 packages

Explanation: 1/2 = 3packages in total she has 2 1/2. So 1/2+ 1/2 = 3 + 3= 6

then again we do 1/2 + 1/2 = 3 + 3 = 6 + 6 = 12 and then since it is 2 1/2 we add 3 again so 12 + 3 = 15 packages
