The below workout with step by step calculation shows how to find what is the difference between two fractions by subtracting a fraction 18/13 from 18/1. For different, unequal or unlike denominators, use any one of the following methods to find the equivalent fraction for 18/1 minus 18/13.
1. LCM method
2. Cross multiplication method.

(18/1) - (18/13) using LCM Method:
What is 18/1 minus 18/13 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 18/1
Fraction B: 18/13

What to be found?
(18/1) - (18/13) = ?
Find what's the difference between 18/1 and 18/13.

step 2 Compare the denominators of fractions 18/1 and 18/13 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 18/1 and 18/13 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 18/1 and 18/13:
The LCM of 1 and 13 is 13.

step 4 Write the fractions 18/1 and 18/13 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 18/1 - 18/13
= [(18 x 13)/(1 x 13)] - [(18 x 13)/(13 x 13)]

step 5 Simplify the expression to have common denominator:
= 234/13 - 18/13

step 6 Take the common values out and rewrite the above expression like the below:
= 1/13 x (234/1 - 18/1)
= 1/13 x (234 - 18)

step 7Simplify the above expression further:
= 1/13 x 216
= 216/13
18/1 - 18/13 = 216/13

Hence,
18/1 minus 18/13 as a fraction is 216/13.
