How to order ratios least to greatest
bezimeni [28]
If you are having trouble with ratios, turn them into fractions.

ex; 3 : 5 = 3/5, 8 : 10 = 8/10, 6 : 15 = 6/15

After you have turned all of your ratios into fractions, you can find a common denominator for all the fractions.
                                                               
ex; 3/5, 8/10, 6/15 ⇒ 3/5, 4/5, 2/5

Now it you can easily order the ratios from least to greatest.

ex; 6 : 15, 3 : 5, 8 : 10

(27576km/h)(1000m/km)(h/3600s)=7660m/s
