Now we're ready to find a percent of any number.
We can calculate percentages by changing the percent to a decimal and multiplying it by the whole. This is good to know when we're shopping.
Let's say a $150 bookshelf is 10% off. What's the discount?
Our whole is $150 (100%). 10% is part of the whole. To find the discount, change the percent to a decimal and multiply it by the whole:
Discount:
10% = 0.10
0.10 × $150 = $15
So 10% of $150 is $15.
