Question

Cindy bought 20 stamps. This is 5 times the number of postcards that Yoshi bought. How many postcards did Yoshi buy

Answer 1

Answer: 4 postcards

Step-by-step explanation: 20/5=4

Answer 2

$5x = 20$
5 times the number (x) is 20. To solve for x you must get rid of the 5, and the opposite of multiplication is divison.
$5x = 20 \\ x = 4$
so 4 postcards :)
