How do you calculate commissions and discounts?

If you have forgotten how to take a percent of a number, below is a brief description of how to do that followed by a video clip demonstrating the same problem.
A percentage is a fraction or ratio of a number with the denominator (the bottom number of a fraction) being 100. For example 25% is the ratio 25/100 which is equivalent to the decimal 0.25. Any percentage can be converted to a decimal by moving the decimal point two places to the left of the decimal if there is one. For example 37% or 37.0% is equivalent to 0.37 or 58.9% is equivalent to 0.589. Notice how the decimal point was moved. Here are some examples of how to take a percent of a number. Example A 14% of 200 When you take a percentage of a number, it is a multiplication problem. So, you can see the multiplication problem that is created in step #2. - Convert 14% to a decimal: 14% = 0.14 or .14
- Write out the new problem: 0.14 x 200
- Do the multiplication: 0.14 x 200= 28.00 or 28
Example B 33.3% of 1,000 - Convert 33.3% to a decimal: 33.3% = 0.333 or .333
- Write out the new problem: 0.333 x 1,000
- Do the multiplication: 0..333 x 1,00= 333
Below is another way of looking at the examples above. Percent |
