Step-by-step explanation:
As a mechanically-oriented person, I think every single previous answer to this question has been incorrect. Certainly, if we compare fractions, 5/8 (or .625) is indeed greater than 3/5 (or .600). But the question is NOT about which fraction is greater, it is asking which RATIO is greater.
Think in terms of a gear ratio in a machine transmission. A 3:5 ratio (note not even expressed at a fraction) means one turn of the input shaft gives 1.667 turns of the output shaft. A 5:8 ratio means one turn of the input shaft gives 1.600 turns of the output shaft. Obviously in considering/using either of these ratios your goal is increased speed, and the 3:5 ratio increases speed more, so 3:5 is the “greater” ratio.
The mathematics here are pretty simple, and we all have our pocket calculators. It seems a bit condescending to interpret this question as a request for math help. My guess is that the question is really about terminology, not math
