The below workout with step by step calculation shows how to find what is the difference between two fractions by subtracting a fraction 2/91 from 1/8. For different, unequal or unlike denominators, use any one of the following methods to find the equivalent fraction for 1/8 minus 2/91.
1. LCM method
2. Cross multiplication method.

(1/8) - (2/91) using LCM Method:
What is 1/8 minus 2/91 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 1/8
Fraction B: 2/91

What to be found?
(1/8) - (2/91) = ?
Find what's the difference between 1/8 and 2/91.

step 2 Compare the denominators of fractions 1/8 and 2/91 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 1/8 and 2/91 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 1/8 and 2/91:
The LCM of 8 and 91 is 728.

step 4 Write the fractions 1/8 and 2/91 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 1/8 - 2/91
= [(1 x 728)/(8 x 728)] - [(2 x 728)/(91 x 728)]

step 5 Simplify the expression to have common denominator:
= 91/728 - 16/728

step 6 Take the common values out and rewrite the above expression like the below:
= 1/728 x (91/1 - 16/1)
= 1/728 x (91 - 16)

step 7Simplify the above expression further:
= 1/728 x 75
= 75/728
1/8 - 2/91 = 75/728

Hence,
1/8 minus 2/91 as a fraction is 75/728.
