# Equivalent Fractions (Fill in missing #)

Students are asked to find the missing term of the following equations. They accomplish this based upon their knowledge of equivalent fractions. Example 4/5 = x/20 x=16 Since I can multiply the denominator 5 in the first fraction by 4 to get to 20. Whatever I do to the denominator I must do to the numerator, then I know 4 x 4 = 16. Therefore, x must be equal to 16.
