In actual life, circumstances may arise where we may need to convert the ratios or Proportions to percentages. This mathematical operations is of wide use in the fields where business analyses, accounting, management of test scores etc. are required to be done. So, how to calculate ratios into percentages? For this we first need to know the fact that the percentages are always measured as per hundred slices. If a Percentage has to be specified as a ratio, the denominator is itself equal to 100. Similarly, to convert the fraction into corresponding percentage we multiply the fraction by 100. Use of scientific calculators may lead to simplified calculations.
Let us consider an example to understand how to convert ratios or Fractions to percentages? Suppose we wish to convert the Ratio 44: 50 or "44 to 50 to its corresponding percentage value. We first replace the colon to from ratio and write it in form of a fraction as 44 /50.
We either multiply fraction by 100 and calculate final result as the percentage value or directly solve fraction and then multiplying it with 100. Let us multiply the fraction by 100 as follows:
44 /50 * 100 = 44 * 2 = 88 %
If we first solve fraction and bring it in decimal form and then multiply decimal number by 100, we get same result:
44 /50 = 0.88
Multiplying it with 100 we get: 0.88 * 100 = 88 % or percent.
Thus we see that, percentages will lie within 100 parts of original value till the numerator in the fraction is less than or equal to the denominator. In case where the numerator goes above the denominator we get percentage value more than 10 percent.
