Question

One day on Snow White’s mail route there were 2920 pieces of mail to be delivered. If 45% of those pieces were advertising pieces, find the number of advertising pieces.

Answer 1

Hello!

You have to find 45% of 2,920

First change 45% to a decimal

To change percents to decimal, remove the % sign and add a decimal point 2 places to the left.

45% = 0.45

Now multiply

0.45 × 2,920 = 1,314

There are 1,314 advertising pieces

Answer 2

turn 45 into a decimal by moving the point two spaces over to the left then do 
0.45 times 2,920 and you will get 1,314. 

therefore, 
your answer is 1,314 :)
