Katie collects trading cards. 15% of her collection are rare cards. If there are a total of 500 cards in Katie's collection, how many of them are rare?
Explanation
To begin, you can set up a proportion:
When trying to find a percent of a number, convert the percent into a decimal. To do this, divide the percent by 100.
You then multiply 500 by 0.15. Since 500 represents 100% of Katie's cards, multiplying by 0.15 will give you how many cards equal 15% of the total.
The result is your answer.
