You can find an equivalent ratio by either simplifying or multiplying your values. To simplify this example, just divide the numerator and denominator by the GCF which is 5
15/5 = 3, 20/5 = 4
So a ratio that is equivalent to 15:20 is 3:4

The first zero after decimal point and 4 only

Step-by-step explanation:
