The way to get equivalent fractions is to multiply the numerator and the denominator by the same number.
4 x 3 = 12
5 x 3 = 15
4/5 = 12/15
In reverse...
The way to reduce fractions is to find the GCF of the numerator and denominator and divide them by it. The GCF of 12 and 15 is 3.
12/3 = 4
15/3 = 5
The GCF of 4 and 5 is 1. That's how you know 4/5 is in its simplest form.
