8.Dolly's mother plans to lose 1 1/4 pounds each week. At this rate how long will it take to lose 15 pounds?

Answer 1

To start you need to find out how many weeks it will take. You can do this by multiplying 1 1/4 or 5/4 *(times) x weeks = 15 lbs. Well we need to find out what x is so we can switch the equation into a division problem. 15 / (5/4) = x weeks. To divide fractions, we "invert and multiply" so multiply (15/1) * (4/5) = (15*4)/(1*5) = (60/5) = 12 Weeks.

Answer 2

Twelve weeks.
