Question

a granola recipe calls for 2 1/3 cups of almonds. A bag of almonds contains 2 cups. To make 2 1/2 batches of granola, Ali buys 5 bags of almonds. How many cups of almonds will he have left over

Answer 1

If Ali bought 5 bags of almonds, then he had 5 * 2 = 10 cups of almonds.

For one granola he needs 2 1/3 cups, so for 2 1/2 batches of granola he'll need 2 1/3 * 2 1/2 of cups:

2 1/3 * 2 1/2 =
= 7/3 * 5/2 =
= 35/6 =
= 5 5/6 [cups]

So if Ali has 10 cups and he'll use 5 5/6 cups, then he'll have 10 - 5 5/6 = 4 1/6 cups left over.
