(18/11) - (5/12) using LCM Method:
What is 18/11 minus 5/12 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 18/11
Fraction B: 5/12

What to be found?
(18/11) - (5/12) = ?
Find what's the difference between 18/11 and 5/12.

step 2 Compare the denominators of fractions 18/11 and 5/12 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 18/11 and 5/12 are not equal, it is said to be unlike fractions subtraction.

The LCM of 11 and 12 is 132.

step 4 Write the fractions 18/11 and 5/12 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 18/11 - 5/12
= [(18 x 132)/(11 x 132)] - [(5 x 132)/(12 x 132)]

step 5 Simplify the expression to have common denominator:
= 216/132 - 55/132

step 6 Take the common values out and rewrite the above expression like the below:
= 1/132 x (216/1 - 55/1)
= 1/132 x (216 - 55)

step 7Simplify the above expression further:
= 1/132 x 161
= 161/132
18/11 - 5/12 = 161/132

Hence,
18/11 minus 5/12 as a fraction is 161/132.
