Ratios are fractions. So, we can divide the top by the bottom to get a decimal form and compare.

10:21 =
(10)/(21)0.47
21:93 =
(21)/(93) ≈ 0.22

0.47 is bigger than 0.22.

So, 10:21 is bigger than 21:93.

So I would change the form of the two ratios. They can also be represented as fractions.

10:21 ⇒ 10/21 = 0.48

21:93 ⇒ 21/93 = 0.23

Therefore, (since 0.48 > 0.23) the ratio 10:21 is greater
