5/6 - 8/7 as a fraction

Learn how to find what is 5/6 minus 8/7 in fraction form just in a few minutes. We have covered the easiest method to write 5/6 - 8/7 as a fraction and decimal.

Summary: 5/6 minus 8/7 = -13/42
Since both fractions have unequal denominators, 5/6 minus 8/7 is an unlike fractions subtraction. For subtracting unlike fractions, you have to first find the equivalent fractions for fraction 5/6 and fraction 8/7 in order to have the same denominators for both fractions. Therefore, you have to find the LCM of denominators 6 and 7. 42 is the LCM of 6 and 7. Multiplying the LCM 42 with the numerators and denominators of both fractions (5/6 x 42/42) - (8/7 x 42/42), and simplify further in order to have the common denominator. So the equivalent fraction for 5/6 is 35/42 and for 8/7 is 48/42. By simplifying this fraction subtraction 35/42 - 48/42, it becomes -13/42.

2. Cross multiplication method.

(5/6) - (8/7) using LCM Method:
What is 5/6 minus 8/7 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 5/6
Fraction B: 8/7

What to be found?
(5/6) - (8/7) = ?
Find what's the difference between 5/6 and 8/7.

step 2 Compare the denominators of fractions 5/6 and 8/7 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 5/6 and 8/7 are not equal, it is said to be unlike fractions subtraction.

step 3For unlike fractions subtraction, find the LCM (least common multiple) of both denominators of fractions 5/6 and 8/7:
The LCM of 6 and 7 is 42.

step 4 Write the fractions 5/6 and 8/7 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 5/6 - 8/7
= [(5 x 42)/(6 x 42)] - [(8 x 42)/(7 x 42)]

step 5 Simplify the expression to have common denominator:
= 35/42 - 48/42

step 6 Take the common values out and rewrite the above expression like the below:
= 1/42 x (35/1 - 48/1)
= 1/42 x (35 - 48)

step 7Simplify the above expression further:
= 1/42 x -13
= -13/42
5/6 - 8/7 = -13/42

Hence,
5/6 minus 8/7 as a fraction is -13/42.
