Fractions can come in many forms and still represent the same amount. Fractions that have different numerators and denominators but possess the same value are called "equivalent" fractions. When a fraction's numerator is greater than its denominator, the fraction is said to be improper and retains a value greater than one. By working with improper fractions, you can find a fraction that is equivalent to a whole number, which can then ease the process of subsequent fractional operations.
Select a number for the fraction's denominator. For this example, let the denominator be 4.
Multiply the denominator to the whole number. For this example, let the whole number be 5 — multiplying 4 by 5 yields 20.

Write the product of the prior step as the numerator over the selected denominator of the first step to create the equivalent fraction. Concluding this example, 20/4 is an equivalent fraction of 5.
The denominator can be any integer — as long as when it is divided into the numerator, it produces the original whole number.
