Given, 1 12 + 1 12 . Like fractions are fractions with the same denominator. To add like fractions, add the numerators and write the same denominator. ⇒ 1 12 + 1 12 = 1 + 1 12 ⇒ 1 12 + 1 12 = 2 12 ⇒ 1 12 + 1 12 = 1 6 Therefore, the required fraction is 1 6 .

Given, 5 9 + 6 9 . Like fractions are fractions with the same denominator. To add like fractions, add the numerators and write the same denominator. ⇒ 5 9 + 6 9 = 5 + 6 9 ⇒ 5 9 + 6 9 = 11 9 Therefore, the required fraction is 11 9 .

Given: 3 5 + 4 5 To add two or more fractions that have the same denominators, add the numerators and place the resulting sum over the common denominator. That is, 3 5 + 4 5 = 3 + 4 7 = 7 5 Now, 7 5 = 1 2 5 Hence, the sum of two fractions is 7 5 or 1 2 5 .
