Judy needs 8 pounds of chicken but at the supermarket the only packages available weighed 3/4th of a pound each. Find the number of packages Judy needs to buy.

Question

Why does Judy have to buy chicken at all in the first place?

Answer 1

Hi, Diksha!

Ok. Judy needs 8 pounds of chicken. We need to find out how many 3/4 pounds are in 8 pounds. Therefore, we need to divide 8 by 3/4.

To do this we write 8 ÷ 3/4.

 To divide by a fraction, we just multiply by its inverse.

So 8 ÷ 3/4 = 8 x 4/3 = 32/3

32/3 = 10 2/3 packages.

Since Judy can't buy 2/3 of a package, she will have to buy 11 packages of chicken.

Now we can check our answer:

11 x 3/4 = 33/4 = 8 1/4 pounds and that sounds right.
