A recipe requires 1.5 cups of flour for 12 cookies. How many cups of flour are needed for 30 cookies?
Show answer & explanation
Correct answer: D
Explanation
Flour for 12 cookies = 1.5 cups
Number of cookies = 30
12 cookies → 1.5 cups
1 cookie → 1.5 / 12 cups
30 cookies → (1.5 / 12) × 30 = 3.75 cups
