Rule in finding equivalent fractions!!! You can change the numbers in a fraction by multiplying or dividing BOTH the numerator and denominator by the SAME number. In other words . . . WHATEVER YOU DO TO THE NUMERATOR, YOU MUST DO TO THE DENOMINATOR! ½ = 2/4 = 3/6 = 4/8 = etc. . . . 1 x 2 = 2 and 2 x 2 = 4, so ½ = 2/4; 1 x3 = 3 and 2 x 3 = 6, so ½ = 3/6; and so on it goes!!!
