4/3 + 3/7 as a fraction

Learn how to find what is 4/3 plus 3/7 in fraction form just in a few minutes. We have covered the easiest method to write 4/3 + 3/7 as a fraction and decimal.

Summary: 4/3 plus 3/7 = 37/21
Since both fractions have unequal denominators, 4/3 plus 3/7 is an unlike fractions addition. For adding unlike fractions, you have to first find the equivalent fractions for fraction 4/3 and fraction 3/7 in order to have the same denominators for both fractions. Therefore, you have to find the LCM of denominators 3 and 7. 21 is the LCM of 3 and 7. Multiplying the LCM 21 with the numerators and denominators of both fractions (4/3 x 21/21) + (3/7 x 21/21), and simplify further in order to have the common denominator. So the equivalent fraction for 4/3 is 28/21 and for 3/7 is 9/21. By simplifying this fraction addition 28/21 + 9/21, it becomes 37/21.

The below workout with step by step calculation shows how to find the equivalent fraction between 4/3 and 3/7 by adding two fractions with different, unequal or unlike denominators. The sum in fraction form for 4/3 plus 3/7 can be obtained by using anyone of the two methods below.
1. LCM method
2. Cross multiplication method.

(4/3) + (3/7) using LCM Method:
What is 4/3 plus 3/7 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 4/3
Fraction B: 3/7

What to be found?
(4/3) + (3/7) = ?
Find what's the sum of 4/3 and 3/7.

step 2 Compare the denominators of fractions 4/3 and 3/7 to identify whether it is a like or unlike fraction addition. Since the denominators of given fractions 4/3 and 3/7 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 3/7:
The LCM of 3 and 7 is 21.

step 4 Write the fractions 4/3 and 3/7 in the addition expression form and multiply LCM with all the numerators and denominators of both fractions.
= 4/3 + 3/7
= [(4 x 21)/(3 x 21)] + [(3 x 21)/(7 x 21)]

step 5 Simplify the expression to have common denominator:
= 28/21 + 9/21

step 6 Take the common values out and rewrite the above expression like the below:
= 1/21 x (28/1 + 9/1)
= 1/21 x (28 + 9)

step 7Simplify the above expression further:
= 1/21 x 37
= 37/21
4/3 + 3/7 = 37/21

Hence,
4/3 plus 3/7 as a fraction is 37/21.
