A recipe for cookies calls for 2/3 of a cup of sugar per batch. Elena used 5 1/3 cups of sugar to make multiple batches of cookies. How many batches did she make? Show your calculation.

8 batches of cookies

Step-by-step explanation:

From the above question, we know that:

2/3 cups of sugar = 1 batch of cookies

Hence:

2/3 cups of sugar = 1 batch of cookies

5 1/3 cups of sugar = x batches

Cross Multiply

2/3 × x = 5 1/3 × 1

x = 5 1/3 / 2/3

x = 5 1/3 ÷ 2/3

x = 16/3 ÷ 2/3

x = 16/3 × 3/2

x = 8 batches of cookies

Therefore, Elena mades 8 batches of cookies with 5 1/3 cups of sugar

step by step explanation: when u removing the parentheses and combined them that would be : x+3y-x-y=2y
