Before learning about how to convert decimal to percent, please read the primer on decimal numbers and the primer on percentages.
You can convert decimal into percentage by shifting the decimal point 2 places to the right and adding a percent sign (%).
Shift the decimal point 2 places to the right
0.1 -> 1.0 -> 10.0 = 10
Add a percent sign
10%
0.1 equals 10%
Again shift the decimal point 2 places to the right
0.75 -> 7.5 -> 75.0 = 75
then add a percent sign
75%
0.75 is equal to 75%
Shift the decimal point 2 places to the right
0.666 -> 6.66 -> 66.6
Add a percent sign
66.6%
0.666 equals 66.6%
Using the steps above practice converting decimal into percentage and create your own chart.
How about this for starters? Add your own results and gradually build your conversion chart!
Grab your calculator and enter 0.1, then the multiply sign (x), followed by 100, and finally the equals sign (=) to give
10
- you've converted the decimal 0.1 to its percentage equivalent 10% on your calculator!
Next check the results of some of the other decimal -> percent examples.
Press the clear button (marked C), enter 0.75, then the x sign, followed by 100, and finally the = sign. The display should show
75
0.75 = 75%
Now press the clear button (C) again, enter 0.666, then the x sign, followed by 100, and finally the = sign. The result of this calculation should be
66.6
0.666 = 66.6%
Follow the same sequence on your calculator to convert the decimals 0.01, 0.025, 0.25, 0.333, 0.5 and 0.999 into their percentage equivalents. Your answers should match those in the right hand column of the chart above.
Using the methods outlined, you'll soon get to grips with converting decimal into percentage with or without your calculator.
