Answer: 1¹/₂ batches
Step-by-step explanation:
Lyndsay is making cookies and 1/3 cup of sugar can make a batch of cookies.
This means that ratio wise, the following is true:
1 batch : 1/3 cups of sugar
If she had only 1/2 cups however, the number of batches she could make using direct proportion is:
1 : 1/3
x : 1/2
1/3x = 1/2
x = 1/2 ÷ 1/3
x = 1/2 * 3/1
x = 3/2
x = 1 1/2 batches
x= 1¹/₂ batches
