(6/7) + (7/12) using LCM Method:
What is 6/7 plus 7/12 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 6/7
Fraction B: 7/12

What to be found?
(6/7) + (7/12) = ?
Find what's the sum of 6/7 and 7/12.

step 2 Compare the denominators of fractions 6/7 and 7/12 to identify whether it is a like or unlike fraction addition. Since the denominators of given fractions 6/7 and 7/12 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 7/12:
The LCM of 7 and 12 is 84.

step 4 Write the fractions 6/7 and 7/12 in the addition expression form and multiply LCM with all the numerators and denominators of both fractions.
= 6/7 + 7/12
= [(6 x 84)/(7 x 84)] + [(7 x 84)/(12 x 84)]

step 5 Simplify the expression to have common denominator:
= 72/84 + 49/84

step 6 Take the common values out and rewrite the above expression like the below:
= 1/84 x (72/1 + 49/1)
= 1/84 x (72 + 49)

step 7Simplify the above expression further:
= 1/84 x 121
= 121/84
6/7 + 7/12 = 121/84

Hence,
6/7 plus 7/12 as a fraction is 121/84.
