This Application Problem is a part of the Lesson 21, Unit 5, Grade 4. This Application Problem builds on the work of Lesson 20 where students learned to add two fractions with related units. This Application Problem bridges to today's lesson where students again add two fractions with related units, but this time, they use number bonds to write the sums as mixed numbers.
