  2. Write a multiplication equation that can describe the same situation.
Show Solution
Solution
  1. 28÷728 \div 7 could represent:
    • How many photos did Han put on each page if he placed 28 photos on 7 pages?
    • How many pages did Han use if he placed 7 photos on each page and 28 photos in total?
  2. Any of the following equations are acceptable:
    • 7⋅?=287 \boldcdot {?} = 28
    • 7⋅4=287 \boldcdot 4 = 28
    • ?⋅7=28{?} \boldcdot 7 = 28
    • 4⋅7=284 \boldcdot 7 = 28
