Which of the following ratios is the largest?
The ratio 3 : 4 is the largest. Converting to decimals gives 0.75, 0.714, 0.70 and 0.667 respectively, so 3 : 4 has the greatest value among the four ratios given.
- A3 : 4Correct
- B5 : 7
- C7 : 10
- D2 : 3
Explanation
Convert each to decimals: 3/4 = 0.75, 5/7 ≈ 0.714, 7/10 = 0.70, 2/3 ≈ 0.667. The largest is 3 : 4. Option 5 : 7 is smaller because 0.714 < 0.75.
