What fraction has a value that's equal to 3/4

There are several fractions with values equal to 3/4. To find them, just multiply the numerator and denominator by the same number.

3 x 2 = 6
4 x 2 = 8

Therefore, 6/8 is equal to 3/4. You could do this with 4, too, to get 12/16, or any other number beyond that.
