Answer:
To convert from a decimal to percent, multiply a decimal by 100 and add the percent sign.
Example: 0.10 becomes 0.10 x 100 = 10%
Example: 0.22 becomes 0.22 x 100 = 22%
To convert from a percent to a decimal, divide a percent by 100 and remove the percent sign.
Example: 10% becomes 10/100 = 0.10
Example: 22% becomes 22/100 = 0.22
Hope this helps!
