Question

Tyra has 1223
cups of sugar. If r is the amount of sugar called for in one batch of cookies,
the expression 1223
÷ r can be used to find how many batches Tyra can make with the sugar she has.
If r is 23
cup, how many batches of cookies can Tyra make?
Enter your answer in the box.

batches

Answer 1

First convert to fractions: 12 2/3 = 38/3.
Divide by r = 2/3: (38/3) ÷ (2/3) = (38/3) × (3/2) = 19.

So Tyra can make 19 batches.
