Multistep Comparison Story Problems: Scale-Factor-Unknown 4-21
Use bar models to solve problems that compare numbers both additively and multiplicatively. If 6 is the smaller number and 42 is the difference, what's the larger number and scale factor? Since the larger number is 6+42 = 48, the scale factor is 48÷6 = 8. 48 is 42 more than 6. 42 is also 8 times as many as 6.
