Answer:

3 to 4

Explanation:

Perhaps you want to reduce the ratio (5/12) to (5/9).

Ratio reduction

You have the ratio of two fractions with the same numerator. The ratio of the fractions will be the inverse of the ratio of their inverses:

(5/12) : (5/9) = (9/5) : (12/5) . . . . . . invert fractions and swap sides

= 9 : 12 = 3 : 4 . . . . . . . . . . . . . multiply by 5 and divide by 3

The ratio (5/12) to (5/9) is 3 to 4.
