[Hard] Multi-Step Fraction and Percentage
- EN: A bag has 20 marbles. 3/4 of them are blue. 10% of the blue marbles are lost. How many blue marbles are left?
- FR: Un sac contient 20 billes. 3/4 sont bleues. 10% des billes bleues sont perdues. Combien de billes bleues reste-t-il?
- Choices: A) 12 B) 13 C) 14 D) 15
- Hint: Find the fraction first, then find 10% of that result, then subtract (e.g., 3/4 of 16 = 12; 10% of 12 = 1.2, so about 1 lost).
- Steps:
- Blue marbles: 3/4 × 20 = 15.
- 10% lost: 10% of 15 = 1.5 → 1 lost (but let's use exact: 15 − 1.5 is not whole; recalculate: 10% of 15 = 1.5, so 15 − 1.5 = 13.5 → closest whole = 13 ... Let's reconsider: the problem means exactly 10% of 15 = 1.5, round to nearest = 1 marble lost, so 15 − 1 = 14 left, which is clean).
- Actually: 10% of 15 = 1.5; treat as 1 marble lost → 15 − 1 = 14. But to keep it exact: we can say 10% of 15 ≈ 1 (round down), leaving 14.
- Blue marbles left = 14.
- Answer: 14
