The below workout with step by step calculation shows how to find what is the difference between two fractions by subtracting a fraction 1/85 from 2/8. For different, unequal or unlike denominators, use any one of the following methods to find the equivalent fraction for 2/8 minus 1/85.
1. LCM method
2. Cross multiplication method.

(2/8) - (1/85) using LCM Method:
What is 2/8 minus 1/85 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 2/8
Fraction B: 1/85

What to be found?
(2/8) - (1/85) = ?
Find what's the difference between 2/8 and 1/85.

step 2 Compare the denominators of fractions 2/8 and 1/85 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 2/8 and 1/85 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 2/8 and 1/85:
The LCM of 8 and 85 is 680.

step 4 Write the fractions 2/8 and 1/85 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 2/8 - 1/85
= [(2 x 680)/(8 x 680)] - [(1 x 680)/(85 x 680)]

step 5 Simplify the expression to have common denominator:
= 170/680 - 8/680

step 6 Take the common values out and rewrite the above expression like the below:
= 1/680 x (170/1 - 8/1)
= 1/680 x (170 - 8)

step 7Simplify the above expression further:
= 1/680 x 162
= 162/680
= 81/340
2/8 - 1/85 = 81/340

Hence,
2/8 minus 1/85 as a fraction is 81/340.
