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 12/5. For different, unequal or unlike denominators, use any one of the following methods to find the equivalent fraction for 12/5 minus 18/11.
1. LCM method
2. Cross multiplication method.
(12/5) - (18/11) using LCM Method:
What is 12/5 minus 18/11 as a fraction?
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 12/5
Fraction B: 18/11
What to be found?
(12/5) - (18/11) = ?
Find what's the difference between 12/5 and 18/11.
step 2 Compare the denominators of fractions 12/5 and 18/11 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 12/5 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 12/5 and 18/11:
The LCM of 5 and 11 is 55.
step 4 Write the fractions 12/5 and 18/11 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 12/5 - 18/11
= [(12 x 55)/(5 x 55)] - [(18 x 55)/(11 x 55)]
step 5 Simplify the expression to have common denominator:
= 132/55 - 90/55
step 6 Take the common values out and rewrite the above expression like the below:
= 1/55 x (132/1 - 90/1)
= 1/55 x (132 - 90)
step 7Simplify the above expression further:
= 1/55 x 42
= 42/55
12/5 - 18/11 = 42/55
Hence,
12/5 minus 18/11 as a fraction is 42/55.
12/5 - 18/11 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 12/5
Fraction B: 18/11
What to be found?
(12/5)-(18/11) = ?
Find what's the difference between 12/5 and 18/11.
step 2 Find the product of numerator of Fraction A and denominator of Fraction B (12 x 11), find the product of numerator of Fraction B and denominator of Fraction A (18 x 5), and find the product of both denominators of Fraction A and Fraction B (5 x 11) and rewrite the equation as like the below:
= (12 x 11) - (18 x 5)/(5 x 11)
step 3 Simplify and rewrite the fraction:
