To convert a percentage to a ratio, write out the percentage number as a fraction, reduce the fraction to its simplest form and convert the new fraction to a ratio by replacing the slash mark with a colon. Converting a percentage to a ratio takes only a few minutes and requires paper and a pencil.Know More
Start by writing out the percentage as a fraction over 100. So, if the percentage is 46 percent, write it as the following: 46/100.
Take the fraction down to its simplest form. The example, 46/100, can be reduced by dividing both numbers by 2, or 2/2. This yields the fraction 23/50, which cannot be reduced further.
Expressing a fraction as a ratio simply means replacing the slash mark with a colon. So, in the example, 23/50 becomes the ratio 23:50.
To reverse the process, turn the ratio back into a fraction. To use a new example, convert the ratio 5:7 into 5/7. Divide the top number by the bottom number. In the example, this yields 0.71. Convert the decimal into a percentage by moving the period two places to the right and adding the percent symbol. In this case, the answer is 71 percent, or 71 percent.
To determine the percentage of a number, divide the fraction of the amount by the whole amount, and multiply the result by 100. As AAA Math explains, to calculate what percentage 68 is of 87, divide 68 by 87; This equals approximately 0.7816. Multiply this answer by 100. The final answer is 78.16 percent.Full Answer >
Converting a percent to a fraction is done by placing the number of the percent over 100. In final form, the fraction needs to contain only integers, and be simplified as much as possible.Full Answer >
The ratio 7 to 12 is written as 7/12 as a fraction in its simplest form. It is not possible to simplify this fraction any further because 7 and 12 have no common factors.Full Answer >
The easiest way to convert a test score to a percentage is to first divide the number of correct answers by the number of total questions. Then, multiplying this ratio by 100 percent gives the percentage score.Full Answer >
