Question

Sue is placing cookies in bags. She has 10 peanut butter cookies and 16 oatmeal cookies. She will place same number of cookies in each bag, and there will be only one type of cookie how many bags will she need

Answer 1

20. Because she can only use 10 of each and one cookie per bag = 20 bags

Answer 2

Sue will need 13 bags in total.

Explanation:

We have to find the bags needed when highest number of cookies is placed in each bag.

We will find the greatest common factor of 16 and 10.

16 = 2 x 2 x 2 x 2

10 = 2 x 5

Greatest common factor is 2.

She will put 2 cookies in each bag.

So, the maximum bags she will need are :

For peanut butter cookies =
`10/2=5`

For oatmeal cookies =
`16/2=8`

Total bags =
`5+8=13`

Therefore, Sue will need 13 bags in total.
