Solution

$28 \div 7$ 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?
Any of the following equations are acceptable:
- $7 \boldcdot {?} = 28$
- $7 \boldcdot 4 = 28$
- ${?} \boldcdot 7 = 28$
- $4 \boldcdot 7 = 28$

Select all representations that describe the same relationship as

6 \boldcdot {?} = 54

does.
