The below workout with step by step calculation shows how to find what is the difference between two fractions by subtracting a fraction 5/7 from 11/4. For different, unequal or unlike denominators, use any one of the following methods to find the equivalent fraction for 11/4 minus 5/7.
1. LCM method
2. Cross multiplication method.

(11/4) - (5/7) using LCM Method:
What is 11/4 minus 5/7 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 11/4
Fraction B: 5/7

What to be found?
(11/4) - (5/7) = ?
Find what's the difference between 11/4 and 5/7.

step 2 Compare the denominators of fractions 11/4 and 5/7 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 11/4 and 5/7 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 11/4 and 5/7:
The LCM of 4 and 7 is 28.

step 4 Write the fractions 11/4 and 5/7 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 11/4 - 5/7
= [(11 x 28)/(4 x 28)] - [(5 x 28)/(7 x 28)]

step 5 Simplify the expression to have common denominator:
= 77/28 - 20/28

step 6 Take the common values out and rewrite the above expression like the below:
= 1/28 x (77/1 - 20/1)
= 1/28 x (77 - 20)

step 7Simplify the above expression further:
= 1/28 x 57
= 57/28
11/4 - 5/7 = 57/28

Hence,
11/4 minus 5/7 as a fraction is 57/28.
