4/3 + 5/4 as a fraction

Learn how to find what is 4/3 plus 5/4 in fraction form just in a few minutes. We have covered the easiest method to write 4/3 + 5/4 as a fraction and decimal.

Summary: 4/3 plus 5/4 = 31/12
Since both fractions have unequal denominators, 4/3 plus 5/4 is an unlike fractions addition. For adding unlike fractions, you have to first find the equivalent fractions for fraction 4/3 and fraction 5/4 in order to have the same denominators for both fractions. Therefore, you have to find the LCM of denominators 3 and 4. 12 is the LCM of 3 and 4. Multiplying the LCM 12 with the numerators and denominators of both fractions (4/3 x 12/12) + (5/4 x 12/12), and simplify further in order to have the common denominator. So the equivalent fraction for 4/3 is 16/12 and for 5/4 is 15/12. By simplifying this fraction addition 16/12 + 15/12, it becomes 31/12.

The below workout with step by step calculation shows how to find the equivalent fraction between 4/3 and 5/4 by adding two fractions with different, unequal or unlike denominators. The sum in fraction form for 4/3 plus 5/4 can be obtained by using anyone of the two methods below.
1. LCM method
2. Cross multiplication method.

(4/3) + (5/4) using LCM Method:
What is 4/3 plus 5/4 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 4/3
Fraction B: 5/4

What to be found?
(4/3) + (5/4) = ?
Find what's the sum of 4/3 and 5/4.

step 2 Compare the denominators of fractions 4/3 and 5/4 to identify whether it is a like or unlike fraction addition. Since the denominators of given fractions 4/3 and 5/4 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 4/3 and 5/4:
The LCM of 3 and 4 is 12.

step 4 Write the fractions 4/3 and 5/4 in the addition expression form and multiply LCM with all the numerators and denominators of both fractions.
= 4/3 + 5/4
= [(4 x 12)/(3 x 12)] + [(5 x 12)/(4 x 12)]

step 5 Simplify the expression to have common denominator:
= 16/12 + 15/12

step 6 Take the common values out and rewrite the above expression like the below:
= 1/12 x (16/1 + 15/1)
= 1/12 x (16 + 15)

step 7Simplify the above expression further:
= 1/12 x 31
= 31/12
4/3 + 5/4 = 31/12

Hence,
4/3 plus 5/4 as a fraction is 31/12.

4/3 + 5/4 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 4/3
Fraction B: 5/4

What to be found?
(4/3)+(5/4) = ?
Find what's the sum of 4/3 and 5/4.

step 2 Find the product of numerator of Fraction A and denominator of Fraction B (4 x 4), find the product of numerator of Fraction B and denominator of Fraction A (5 x 3), and find the product of both denominators of Fraction A and Fraction B (3 x 4) and rewrite the equation as like the below:
= (4 x 4) + (5 x 3)/(3 x 4)

step 3 Simplify and rewrite the fraction:
= (16 + 15)/12
