Show the answer and the worked solution
Correct answer: B. 24
Worked solution
- Total parts = 5, so one part = 60 ÷ 5 = 12.
- Smaller part = 2 × 12 = 24.
Answer: 24.
The idea
Divide by the sum of the ratio terms to size one part, then multiply. The two parts should add back to the original total.
Shortcut. The smaller part is 2/5 of 60, which is 40% of 60 = 24.
Common trap. "36" — sizing one part at 12 but multiplying by 3, which gives the larger part.
