The below workout with step by step calculation shows how to find what is the difference between two fractions by subtracting a fraction 1/87 from 2/40. For different, unequal or unlike denominators, use any one of the following methods to find the equivalent fraction for 2/40 minus 1/87.
1. LCM method
2. Cross multiplication method.

(2/40) - (1/87) using LCM Method:
What is 2/40 minus 1/87 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 2/40
Fraction B: 1/87

What to be found?
(2/40) - (1/87) = ?
Find what's the difference between 2/40 and 1/87.

step 2 Compare the denominators of fractions 2/40 and 1/87 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 2/40 and 1/87 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 2/40 and 1/87:
The LCM of 40 and 87 is 3480.

step 4 Write the fractions 2/40 and 1/87 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 2/40 - 1/87
= [(2 x 3480)/(40 x 3480)] - [(1 x 3480)/(87 x 3480)]

step 5 Simplify the expression to have common denominator:
= 174/3480 - 40/3480

step 6 Take the common values out and rewrite the above expression like the below:
= 1/3480 x (174/1 - 40/1)
= 1/3480 x (174 - 40)

step 7Simplify the above expression further:
= 1/3480 x 134
= 134/3480
= 67/1740
2/40 - 1/87 = 67/1740

Hence,
2/40 minus 1/87 as a fraction is 67/1740.
