5/4 + 1/9 as a fraction

Learn how to find what is 5/4 plus 1/9 in fraction form just in a few minutes. We have covered the easiest method to write 5/4 + 1/9 as a fraction and decimal.

Summary: 5/4 plus 1/9 = 49/36
Since both fractions have unequal denominators, 5/4 plus 1/9 is an unlike fractions addition. For adding unlike fractions, you have to first find the equivalent fractions for fraction 5/4 and fraction 1/9 in order to have the same denominators for both fractions. Therefore, you have to find the LCM of denominators 4 and 9. 36 is the LCM of 4 and 9. Multiplying the LCM 36 with the numerators and denominators of both fractions (5/4 x 36/36) + (1/9 x 36/36), and simplify further in order to have the common denominator. So the equivalent fraction for 5/4 is 45/36 and for 1/9 is 4/36. By simplifying this fraction addition 45/36 + 4/36, it becomes 49/36.

The below workout with step by step calculation shows how to find the equivalent fraction between 5/4 and 1/9 by adding two fractions with different, unequal or unlike denominators. The sum in fraction form for 5/4 plus 1/9 can be obtained by using anyone of the two methods below.
1. LCM method
2. Cross multiplication method.

(5/4) + (1/9) using LCM Method:
What is 5/4 plus 1/9 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 5/4
Fraction B: 1/9

What to be found?
(5/4) + (1/9) = ?
Find what's the sum of 5/4 and 1/9.

step 2 Compare the denominators of fractions 5/4 and 1/9 to identify whether it is a like or unlike fraction addition. Since the denominators of given fractions 5/4 and 1/9 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 5/4 and 1/9:
The LCM of 4 and 9 is 36.

step 4 Write the fractions 5/4 and 1/9 in the addition expression form and multiply LCM with all the numerators and denominators of both fractions.
= 5/4 + 1/9
= [(5 x 36)/(4 x 36)] + [(1 x 36)/(9 x 36)]

step 5 Simplify the expression to have common denominator:
= 45/36 + 4/36

step 6 Take the common values out and rewrite the above expression like the below:
= 1/36 x (45/1 + 4/1)
= 1/36 x (45 + 4)

step 7Simplify the above expression further:
= 1/36 x 49
= 49/36
5/4 + 1/9 = 49/36

Hence,
5/4 plus 1/9 as a fraction is 49/36.
