Kevin makes snack bags that each contain a box of raisins and a granola bar. Each package of raisins contains 9 boxes. The granola bars come 12 to a package. What is the least number he can buy of each so he has exactly the same number of each. How many packages of each should he buy?

Answer 1

You must find the least common multiple so he will have the exact same number of each item
9,18,27,36
12,24,36

Answer 2

Answer with explanation:

Given : Kevin makes snack bags that each contain a box of raisins and a granola bar. Each package of raisins contains 9 boxes. The granola bars come 12 to a package.

Now,

`12=2*2*3\\\\9=3*3`

The least number he can buy of each so he has exactly the same number of each will be :-

`\text{LCM (9,12)=}3*3*2*2=36`

Number of raisins bag he should buy =
`(36)/(9)=4`

Number of granola bars package he should buy =
`(36)/(12)=3`
