The same amount of orange juice fills ¾ of a small jug or ½ of a large jug. What fraction of the large jug's capacity is the small jug's capacity?
- 1/6
- 2/3
- 3/8
- 4/6
Answer: 2/3. If the juice is amount J: small jug = J ÷ (3/4) = 4J/3. Large jug = J ÷ (1/2) = 2J. Ratio: (4J/3) / (2J) = (4/3) / 2 = 4/6 = 2/3.
