How to convert a number from decimal to percent is the goal of this lesson.
In a nutshell, all you need to do is to move the decimal point two places to the right and adding the percent symbol.
Step 1.
Move the decimal point two places to the right.
Step 2.
Remove unnecessary zeros on the left of the number.
Step 3.
Remove the decimal point that was moved two places to the right if step 2 gave a whole number. Otherwise, keep the decimal point.
Step 4.
Add the percent sign or % to the right of the number.
Example #1:
Change 0.123 to a percent.
Step 1.
Move the decimal point two places to the right. This means that you will place the decimal point between the 2 and the 3.
We get 012.3.
Step 2.
Remove any unnecessary zero(s) on the left of the number.
We get 12.3.
Step 3.
Remove the decimal point that was moved two places to the right if step 2 gave a whole number. Otherwise, keep the decimal point.
12.3 is not a whole number, so keep decimal point.
Step 4.
Add the percent sign or % to the right of the number.
The answer is 12.3%
Notice that there is no need to write the decimal point if it occurs at the end of the number.
Notice also that moving the decimal point to the right two places is the same thing as multiplying the number by 100.
It is the inverse of dividing by 100 to convert to a decimal when the number is given as a percent.
