(5/6) - (9/7) using LCM Method:
What is 5/6 minus 9/7 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 5/6
Fraction B: 9/7

What to be found?
(5/6) - (9/7) = ?
Find what's the difference between 5/6 and 9/7.

step 2 Compare the denominators of fractions 5/6 and 9/7 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 5/6 and 9/7 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 9/7:
The LCM of 6 and 7 is 42.

step 4 Write the fractions 5/6 and 9/7 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 5/6 - 9/7
= [(5 x 42)/(6 x 42)] - [(9 x 42)/(7 x 42)]

step 5 Simplify the expression to have common denominator:
= 35/42 - 54/42

step 6 Take the common values out and rewrite the above expression like the below:
= 1/42 x (35/1 - 54/1)
= 1/42 x (35 - 54)

step 7Simplify the above expression further:
= 1/42 x -19
= -19/42
5/6 - 9/7 = -19/42

Hence,
5/6 minus 9/7 as a fraction is -19/42.
