Percents with fractions: Definition, Problems and Solutions

 Percents with fractions

Percent to Fraction definition

The term “percent” is made up of two words ‘per and cent’ which means “Out of 100”. In other words, we can say that percent is the ratio calculated out of 100.  For Example , if in an examination , Rahul got  87 % marks that means Rahul has got   87 marks out of 100.  The symbol for percent  is “%” . It means “out of 100” .

Another way to visualize percent , you can take whole of something and divide it into 100 little pieces and then figure out how many little pieces are in the portion you are interested in. Far example ,If we divide a pizza into 100 little slices , then each slice would represent 1% of the pizza. If you wanted a quarter of the pizza, you would see that it would require 25 slices out of 100 or 25 % of the pizza. If you want half of pizza, it would be 50% or half of hundred percent.

50 percent
           1% =\frac{1}{100}                    25%= \frac{1}{4}                     50% = \frac{1}{2}

The percent to fraction is the conversion of percentage values to a fraction. Any percent is easy to be converted to a fraction and vice versa. The steps to convert percent into fractions are given below.
