Formative Performance Task Formative Performance Task Formative Performance Task Steps for solving multiplying a fraction by a fraction problem: 1. If there is a mixed number then If my mother is ½ Irish and my father If my mother is ¾ Native American convert to an improper is 1/8 Irish. What fraction Irish am I? and my father is 1/8 Native fraction. American then what fraction of 2. Multiply the numerators times 1. What fraction of Irish do I get Native American am I? each other. from my mother? ½ of ½ so 3. Multiply the denominators multiply ½ X 1/2 = ¼. 1. ½ times ¾ from my mother = times each other. 2. What fraction of Irish do I get 3/8 4. Simplify if the numerator and from my father? 1/2 X 1/8 = 2. ½ times 1/8 from my father denominator are each divisible 1/16. = 1/16 by a number other than one. 3. Now add the fractions 3. Add 3/8 + 1/16 = 5. Change from an improper together. ¼ + 1/16 = 5/16 6/16 + 1/16 = 7/16 fraction to a mixed number if the numerator is larger than the denominator.
