Write a statement that compares the cost of the card game and the cost of the video game.
Write a multiplication equation that compares the cost of the card game and the cost of the video game.

Show Solution

Solution

Sample responses:

The cost of the video game is 7 times as much as the cost of the card game.
$7 \times {?} = 42$ or ${?} \times 7 = 42$ or $7 \times 6 = 42$ or $6 \times 7 = 42$

Problem 2

Han ran 12 miles in a week. That's 3 times as far as Andre ran. How many miles did Andre run during the week? Explain or show your reasoning.

Show Solution

Solution

4 miles. Sample responses:

Students draw a diagram to show the multiplicative comparison.
Andre ran 4 miles because $12 \div 3 = 4$ .
$3\times?=12$ , so Andre ran 4 miles.
