Frank needs to fill juice cups for his little sister's birthday party there are 35 juice cups and each juice cup holds 12 fluid ounces the juice comes in one gallon bottles how many one gallon bottles of juice will frank need to purchase

He will need to buy 4 of one gallon bottles

How?-
35 x 12 = 420 fluid ounces needed

1 Quart = 32 fluid ounces, so

420/32=13.125 quarts

1 Gallon = 4 quarts, so

13.125/4= 3.28125, so he will need 4 bottles to fill all the cups because how are you going to buy 3.28125 bottles so you would round that to 4

4 gal. because there are 128 oz. in a gal. 35 times 12 = 420. 4gals is 512 oz.

There is no question, there is just the answer.
