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.
