Learn how to find what is 3/2 minus 18/11 in fraction form just in a few minutes. We have covered the easiest method to write 3/2 - 18/11 as a fraction and decimal.

Summary: 3/2 minus 18/11 = -3/22
Since both fractions have unequal denominators, 3/2 minus 18/11 is an unlike fractions subtraction. For subtracting unlike fractions, you have to first find the equivalent fractions for fraction 3/2 and fraction 18/11 in order to have the same denominators for both fractions. Therefore, you have to find the LCM of denominators 2 and 11. 22 is the LCM of 2 and 11. Multiplying the LCM 22 with the numerators and denominators of both fractions (3/2 x 22/22) - (18/11 x 22/22), and simplify further in order to have the common denominator. So the equivalent fraction for 3/2 is 33/22 and for 18/11 is 36/22. By simplifying this fraction subtraction 33/22 - 36/22, it becomes -3/22.

The below workout with step by step calculation shows how to find what is the difference between two fractions by subtracting a fraction 18/11 from 3/2. For different, unequal or unlike denominators, use any one of the following methods to find the equivalent fraction for 3/2 minus 18/11.
1. LCM method
2. Cross multiplication method.

(3/2) - (18/11) using LCM Method:
What is 3/2 minus 18/11 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 3/2
Fraction B: 18/11

What to be found?
(3/2) - (18/11) = ?
Find what's the difference between 3/2 and 18/11.

step 2 Compare the denominators of fractions 3/2 and 18/11 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 3/2 and 18/11 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 3/2 and 18/11:
The LCM of 2 and 11 is 22.

step 4 Write the fractions 3/2 and 18/11 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 3/2 - 18/11
= [(3 x 22)/(2 x 22)] - [(18 x 22)/(11 x 22)]

step 5 Simplify the expression to have common denominator:
= 33/22 - 36/22

step 6 Take the common values out and rewrite the above expression like the below:
= 1/22 x (33/1 - 36/1)
= 1/22 x (33 - 36)

step 7Simplify the above expression further:
= 1/22 x -3
= -3/22
3/2 - 18/11 = -3/22

Hence,
3/2 minus 18/11 as a fraction is -3/22.
