Do these ratios form a proportion? 3 large sweatshirts for every 9 small sweatshirts

12 large sweatshirts for every 36 small sweatshirts

yes or no

Yes

Step-by-step 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.

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).
