7/5 + 3/7 as a fraction

Learn how to find what is 7/5 plus 3/7 in fraction form just in a few minutes. We have covered the easiest method to write 7/5 + 3/7 as a fraction and decimal.

Summary: 7/5 plus 3/7 = 64/35
Since both fractions have unequal denominators, 7/5 plus 3/7 is an unlike fractions addition. For adding unlike fractions, you have to first find the equivalent fractions for fraction 7/5 and fraction 3/7 in order to have the same denominators for both fractions. Therefore, you have to find the LCM of denominators 5 and 7. 35 is the LCM of 5 and 7. Multiplying the LCM 35 with the numerators and denominators of both fractions (7/5 x 35/35) + (3/7 x 35/35), and simplify further in order to have the common denominator. So the equivalent fraction for 7/5 is 49/35 and for 3/7 is 15/35. By simplifying this fraction addition 49/35 + 15/35, it becomes 64/35.

The below workout with step by step calculation shows how to find the equivalent fraction between 7/5 and 3/7 by adding two fractions with different, unequal or unlike denominators. The sum in fraction form for 7/5 plus 3/7 can be obtained by using anyone of the two methods below.
1. LCM method
2. Cross multiplication method.

(7/5) + (3/7) using LCM Method:
What is 7/5 plus 3/7 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 7/5
Fraction B: 3/7

What to be found?
(7/5) + (3/7) = ?
Find what's the sum of 7/5 and 3/7.

step 2 Compare the denominators of fractions 7/5 and 3/7 to identify whether it is a like or unlike fraction addition. Since the denominators of given fractions 7/5 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 7/5 and 3/7:
The LCM of 5 and 7 is 35.

step 4 Write the fractions 7/5 and 3/7 in the addition expression form and multiply LCM with all the numerators and denominators of both fractions.
= 7/5 + 3/7
= [(7 x 35)/(5 x 35)] + [(3 x 35)/(7 x 35)]

step 5 Simplify the expression to have common denominator:
= 49/35 + 15/35

step 6 Take the common values out and rewrite the above expression like the below:
= 1/35 x (49/1 + 15/1)
= 1/35 x (49 + 15)

step 7Simplify the above expression further:
= 1/35 x 64
= 64/35
7/5 + 3/7 = 64/35

Hence,
7/5 plus 3/7 as a fraction is 64/35.
