6/7 + 1/8 as a fraction

Learn how to find what is 6/7 plus 1/8 in fraction form just in a few minutes. We have covered the easiest method to write 6/7 + 1/8 as a fraction and decimal.

Summary: 6/7 plus 1/8 = 55/56
Since both fractions have unequal denominators, 6/7 plus 1/8 is an unlike fractions addition. For adding unlike fractions, you have to first find the equivalent fractions for fraction 6/7 and fraction 1/8 in order to have the same denominators for both fractions. Therefore, you have to find the LCM of denominators 7 and 8. 56 is the LCM of 7 and 8. Multiplying the LCM 56 with the numerators and denominators of both fractions (6/7 x 56/56) + (1/8 x 56/56), and simplify further in order to have the common denominator. So the equivalent fraction for 6/7 is 48/56 and for 1/8 is 7/56. By simplifying this fraction addition 48/56 + 7/56, it becomes 55/56.

The below workout with step by step calculation shows how to find the equivalent fraction between 6/7 and 1/8 by adding two fractions with different, unequal or unlike denominators. The sum in fraction form for 6/7 plus 1/8 can be obtained by using anyone of the two methods below.
1. LCM method
2. Cross multiplication method.

(6/7) + (1/8) using LCM Method:
What is 6/7 plus 1/8 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 6/7
Fraction B: 1/8

What to be found?
(6/7) + (1/8) = ?
Find what's the sum of 6/7 and 1/8.

step 2 Compare the denominators of fractions 6/7 and 1/8 to identify whether it is a like or unlike fraction addition. Since the denominators of given fractions 6/7 and 1/8 are not equal, it is said to be unlike fractions addition.

step 3For unlike fractions addition, find the LCM (least common multiple) of both denominators of fractions 6/7 and 1/8:
The LCM of 7 and 8 is 56.

step 4 Write the fractions 6/7 and 1/8 in the addition expression form and multiply LCM with all the numerators and denominators of both fractions.
= 6/7 + 1/8
= [(6 x 56)/(7 x 56)] + [(1 x 56)/(8 x 56)]

step 5 Simplify the expression to have common denominator:
= 48/56 + 7/56

step 6 Take the common values out and rewrite the above expression like the below:
= 1/56 x (48/1 + 7/1)
= 1/56 x (48 + 7)

step 7Simplify the above expression further:
= 1/56 x 55
= 55/56
6/7 + 1/8 = 55/56

Hence,
6/7 plus 1/8 as a fraction is 55/56.
