11/4 + 3/2 as a fraction

Learn how to find what is 11/4 plus 3/2 in fraction form just in a few minutes. We have covered the easiest method to write 11/4 + 3/2 as a fraction and decimal.

Summary: 11/4 plus 3/2 = 17/4
Since both fractions have unequal denominators, 11/4 plus 3/2 is an unlike fractions addition. For adding unlike fractions, you have to first find the equivalent fractions for fraction 11/4 and fraction 3/2 in order to have the same denominators for both fractions. Therefore, you have to find the LCM of denominators 4 and 2. 4 is the LCM of 4 and 2. Multiplying the LCM 4 with the numerators and denominators of both fractions (11/4 x 4/4) + (3/2 x 4/4), and simplify further in order to have the common denominator. So the equivalent fraction for 11/4 is 11/4 and for 3/2 is 6/4. By simplifying this fraction addition 11/4 + 6/4, it becomes 17/4.

CALCULATION: 11/4 + 3/2 as a fraction

The below workout with step by step calculation shows how to find the equivalent fraction between 11/4 and 3/2 by adding two fractions with different, unequal or unlike denominators. The sum in fraction form for 11/4 plus 3/2 can be obtained by using anyone of the two methods below.
1. LCM method
2. Cross multiplication method.

(11/4) + (3/2) using LCM Method:
What is 11/4 plus 3/2 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 11/4
Fraction B: 3/2

What to be found?
(11/4) + (3/2) = ?
Find what's the sum of 11/4 and 3/2.

step 2 Compare the denominators of fractions 11/4 and 3/2 to identify whether it is a like or unlike fraction addition. Since the denominators of given fractions 11/4 and 3/2 are not equal, it is said to be unlike fractions addition.

step 3For unlike fractions addition, find the LCM (least common multiple) of both denominators of fractions 11/4 and 3/2:
The LCM of 4 and 2 is 4.

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

step 5 Simplify the expression to have common denominator:
= 11/4 + 6/4

step 6 Take the common values out and rewrite the above expression like the below:
= 1/4 x (11/1 + 6/1)
= 1/4 x (11 + 6)

step 7Simplify the above expression further:
= 1/4 x 17
= 17/4
11/4 + 3/2 = 17/4

Hence,
11/4 plus 3/2 as a fraction is 17/4.
