How do you find the equivalency of a fraction?

Answer 1

Two fractions are equivalent if their cross products are equal. That is,

A/B = C/D if A*D = B*C

Answer 2

To find the equivalency of a fraction, you can multiply both the numerator and denominator by the same number. This will result in a fraction that is equivalent to the original one but has different numbers. For example, if you multiply both the numerator and denominator of 1/2 by 2, you get 2/4, which is an equivalent fraction.
