The below workout with step by step calculation shows how to find what is the difference between two fractions by subtracting a fraction 1/77 from 2/4. For different, unequal or unlike denominators, use any one of the following methods to find the equivalent fraction for 2/4 minus 1/77.
1. LCM method
2. Cross multiplication method.

(2/4) - (1/77) using LCM Method:
What is 2/4 minus 1/77 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 2/4
Fraction B: 1/77

What to be found?
(2/4) - (1/77) = ?
Find what's the difference between 2/4 and 1/77.

step 2 Compare the denominators of fractions 2/4 and 1/77 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 2/4 and 1/77 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 2/4 and 1/77:
The LCM of 4 and 77 is 308.

step 4 Write the fractions 2/4 and 1/77 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 2/4 - 1/77
= [(2 x 308)/(4 x 308)] - [(1 x 308)/(77 x 308)]

step 5 Simplify the expression to have common denominator:
= 154/308 - 4/308

step 6 Take the common values out and rewrite the above expression like the below:
= 1/308 x (154/1 - 4/1)
= 1/308 x (154 - 4)

step 7Simplify the above expression further:
= 1/308 x 150
= 150/308
= 75/154
2/4 - 1/77 = 75/154

Hence,
2/4 minus 1/77 as a fraction is 75/154.
