(A divided by b) + (c divided by d)= (a multiplied by d) + (b multiplied by c)/ (b multiplied by d)

Formula of Adding Mixed Numbers

Here, we will see the formula of adding mixed numbers.

Formula, (a/b)+(c/d) = (a * d) + (b * C)/ (b *d).


a/b, c/d are fractions.

a,b,c,d are integers.

Steps for Adding Mixed Fractions

Adding Mixed Numbers with Example


Question: Calculate addition of 12(5/7), 17(3/5)?


Given, mixed numbers are 12(5/7) and 17(3/5)

Addition : 12(5/7) + 17(3/5)

Convert mixed numbers to improper fractions.

Mixed number 1: 12(5/7) = (84 +5) / 7 = 89/7

Mixed number 2: 17(3/5) = (85 +3) / 5 = 88/5

Formula of adding two numbers

a/b + c/d = ad + bc / bd

Add the two fractions

(89 x 5) + (88 x 7) / (7 x 5)

(445 + 616)/ 35


Change the fraction into mixed number

1061/35 = 30(11/35)
