Answer:
3/8 cup
Step-by-step explanation:
To figure out how many cups of flour he could use, let's convert the fractions into decimals. We are told that amount he needs is less than 1/2 and more than 1/3.
1/2 = 0.50
1/3 = 0.33
So, the amount he needs is less than 0.50 and more than 0.33. Now let's convert the answer choices to decimal form:
1/4 = 0.25
7/12 = 0.58
3/8 = 0.38
7/8 = 0.88
The only answer choice that is less than 0.50 but greater than 0.33 is 0.38, or 3/8 cup.
