the table lists sizes of packages of school supplies. what is the smallest number of pencils and erasers that mrs. Deng can buy so that she will have the same number of each?
The answer would be C) 60 because you can't add 10 multiple times and get 24, you can't add 12 multiple times and get 30, and though both numbers can add up to 120, 60 is the smaller amount.
