3 large sweatshirts for every 9 small sweatshirts

12 large sweatshirts for every 36 small sweatshirts

yes or no

Answer 1

Yes

You cross multiply

Answer 2

Yes

Explanation:

3/9=12/36 because of cross multiplying: multiply the outside terms and the inside terms. They should equal each other. 3x36=12x9 and 108=108. So, yes.
