Multiply Fractions by Whole Numbers Equal-Groups Word Problems 5-64

Use story problems to provide context. Draw bar models to visualize the part-whole relationship. What is 1/5 of a bag of 85 legos? The total or "whole" is 85 legos. Find 1/5 by dividing 85 into 5 equal groups. Since 85÷5 = (50+35)÷5 = 17, 1/5 x 85 = 17. Start with unit fractions. Transition to proper fractions.
