We are going to learn how to convert between decimals, fractions and percent.
Decimal to Percent
To change a decimal to a percent, move the decimal to the right two times and add the percent sign.
We move the decimal twice because .34 = 34%
percent means out of 100, and from our mental math multiplying by 100 moves the decimal twice to the right.
.035 2.13 .245 10

Percent to Decimal
To change a percent to a decimal, move the decimal to the left two times and get rid of the percent sign.

To change a percent to a fraction, put the percent over 100 and reduce.

100 20 100 x10
decimal in our fraction so we need to multiply the top and bottom by a power of ten, in this case 10.
