how much milk to use when making pancakes

Question

if someone uses 2 3/4 of milk when making one batch of pancake how much milk will they need to use to make 3 batches ?

Answer 1

Whenever you have a question like this, set it up as a ratio. In this case, cups of milk over batches of pancakes.

2.75/1 = c/3

2.75 is the 2 and 3/4 cups of milk. 1 is the batch of pancakes. C is the cups of milk we don't know. 3 is the batches of pancakes we want to make.

Now you cross multiply -- multiply the top of one fraction by the bottom of the other, then multiply the bottom of the first fraction by the top of the other.

2.75 x 3 = 1 x c

Since 1 x c = c, your answer is c = 8.25. You will need 8.25 (or 8 1/4) cups of milk to make 3 batches of pancakes.
