In the Part 1, we have learned how to convert fraction to percent by relating the denominator to 100 by multiplication or division. In this post, we do its ‘algebraic version.’ This method is a generalized method to the previous post especially for numbers that do not divide 100 or cannot be divided by 100 easily. However, to see the relationship between the two methods, let us do the first example in Part 1 of this series.
Example 1: What is the equivalent of 1/5 in percent.
Recall that in Part 1, we multiplied both the numerator and the denominator by 20, to make the denominator 100. That is, Continue reading
