Which of the following ratios is the greatest?

To find the greatest ratio, compare their fractional values:

37 : 76 = $ \frac{37}{76} \approx 0.487 $
43 : 65 = $ \frac{43}{65} \approx 0.662 $
35 : 72 = $ \frac{35}{72} \approx 0.486 $
50 : 60 = $ \frac{50}{60} = \frac{5}{6} \approx 0.833 $

Clearly, the largest value is:

✅ 50 : 60
