Decimal to percent
To go from decimal to percent, all you need to do is to move the decimal point two places to the right and adding the percent symbol.
Examples:
Change 0.123 to a percent
Place the decimal point between the 2 and the 3
We get: 12.3
Add the percent symbol: %
The answer is 12.3 %
Example:
Change 0.50 to a percent
Place the decimal point after the 0
We get 50
Add the percent symbol: %
The answer is 50 %
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.
Example:
Change 0.0000256 to a percent
Move the decimal point two places to the right
We get 0.00256
Add the percent symbol: %
The answer is 0.00256 %
