Ratios are easier to picture if we reduce them to lowest terms.
Let's reduce the ratio 24:36.
Find the largest number that divides evenly into both 24 and 36. In this case, the largest number that divides evenly into both 24 and 36 is 12.
24/12 = 2
36/12 = 3
So, the reduced ratio is 2:3.
Check that no number other than 1 divides evenly into both terms in the ratio 2:3.
If that's the case, the ratio is written in the lowest terms.
