A recipe uses 3 cups of flour for every 2 cups of sugar. If you use 9 cups of flour, how many cups of sugar do you need?

Correct answer

6 cups

  1. A 4 cups
  2. B 6 cups
  3. C 5 cups
  4. D 8 cups

Why this is the answer

Set up a PROPORTION: flour/sugar = 3/2 = 9/x. Cross-multiply: 3x = 2 × 9 = 18, so x = 6 cups of sugar. ASVAB Arithmetic Reasoning tests ratios/proportions. SHORTCUT: 9 cups of flour is 3 times the original 3 cups (9 ÷ 3 = 3), so multiply the sugar by 3 too: 2 × 3 = 6 cups. Strategy: keep the ratio consistent — whatever you multiply one part by, multiply the other part by the same factor. Check: 9/6 reduces to 3/2. ✓
