What is a Fraction

What is a Fraction Fraction is a number which is written in the form a/b where a and b are any integers except b 0. Fractions are written in this form and hence they have numerator and a denominator. The place where the number is written in the top of the fraction is known as the numerator and the place where a number is written in the bottom is known as the denominator of the fraction. Fractions can be simplified further if possible and be converted to various other number forms. Example 1: Add the given two fractions: 3/8 + 1/8. Given expression: 3/8 + 1/8 Here both 3/8 and 1/8 are fractions and they are being added together. In order to add or subtract two fractions, we have to make sure that the fractions have the same denominator. Both 3/8 and 1/8 have the same denominator 8, hence they can be added directly! This gives: 3/8+1/8 = (3+ 1)/8= 4/8. 4/8 can be simplified by dividing the top and the bottom by the factor 4==4/8= 1/2 Therefore, 3/8+ 1/8 = 4/8 = 1/2 Example 2:Subtract the given two fractions: 17/4 5/4. Given expression: 17/4 5/4 Here both 17/4 and 5/4 are fractions and they are being subtracted together. In order to add or subtract two fractions, we have to make sure that the fractions have the same denominator. Both 17/4 and 5/4 have the same denominator 4, hence they can be subtracted directly! This gives: 17/4- 5/4 = (17- 5)/4= 12/4. 12/4 can be simplified by dividing the top and the bottom by the factor 4==12/4= 3/1. Therefore,17/4- 5/4 = 12/4 = 3/1.
