The easiest to find equivalent fractions is to multiply both the numerator and denominator by the same integer.
For Example, an equivalent fraction for 9/15 is 18/30. I got this answer by multiplying 9*2=18 and 15*2=30.
Another equivalent fraction for 9/15 is 27/45 because 9*3=27 and 15*3=45.
******Note
Just make sure that you always multiply the numerator and denominator by the same number, or else your fractions won't be equivalent!!
