Pre-Algebra: Lesson 035

Fractions and Mixed Numbers
Equivalent Fractions (Part I)

Lesson Description

Students learn to write equivalent fractions that represent the shaded part of given figures. Students also learn that multiplying or dividing the numerator and denominator of a given fraction by the same number results in an equivalent fraction. For example, multiplying the numerator and denominator of 5/12 by 2 results in the equivalent fraction 10/24. Students are also asked to find the value of the variable that makes given fractions equivalent. For example, if 3/7 = 9/d, then the value of d that makes the fractions equivalent is 21.
