jeka57 [31]

Answer:

Medium: 4 and Large: 6

Step-by-step explanation:

Factor pairs that are equivalent to 10:

1,9

2,8

3,7

4,6

5,5

and so on. So you could do 2.4*9 and 1.8*1. If that doesn't work, switch it around. This coud probably take 1/2 of a hour or more. But it'll be worth it if it's a grade. :3

In the end, I'm pretty sure you should be able to get the answer:

Medium cups: 4

Large cups: 6

1.8 multiplied by 4 would get you 7.2 and 2.4 multiplied by 6 would get you 14.4. If you add them all up, you would get a 21.6! If you didn't, check your math again.
