Answer:

Step-by-step explanation:

120 x .45 = 54; and to check

54 ÷ 120 = 0.45

First you move the decimal point to the right 2 spaces to change the percent (%) to a decimal (change 45% to .45); and then you multiply by the 120. So it turns into

.45 x 120 = 54 the answer is: 54

To check you go in the opposite direction. Move the decimal point to the right ( 45 x 120 ) and the answer is 5400; which is a whole number, which means the decimal is invisibly at the end; then move the decimal point back two spaces to the left and it now looks like this 54.00; which is a whole number and the two zeros at the end can be taken off; there's that invisible decimal that makes it a whole number that you p.s. don't ever need... You are right back to 54 :)

Hope that helps! <3

If you add $47 to $17 multiplied by two, then the total cost would be $81 because 17 multiplied by two is 34, and 47 added to 34 is 81, so the total amount paid would be $81.
