7/1 + 3/5 as a fraction

Learn how to find what is 7/1 plus 3/5 in fraction form just in a few minutes. We have covered the easiest method to write 7/1 + 3/5 as a fraction and decimal.

Summary: 7/1 plus 3/5 = 38/5
Since both fractions have unequal denominators, 7/1 plus 3/5 is an unlike fractions addition. For adding unlike fractions, you have to first find the equivalent fractions for fraction 7/1 and fraction 3/5 in order to have the same denominators for both fractions. Therefore, you have to find the LCM of denominators 1 and 5. 5 is the LCM of 1 and 5. Multiplying the LCM 5 with the numerators and denominators of both fractions (7/1 x 5/5) + (3/5 x 5/5), and simplify further in order to have the common denominator. So the equivalent fraction for 7/1 is 35/5 and for 3/5 is 3/5. By simplifying this fraction addition 35/5 + 3/5, it becomes 38/5.

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

(7/1) + (3/5) using LCM Method:
What is 7/1 plus 3/5 as a fraction?

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

What to be found?
(7/1) + (3/5) = ?
Find what's the sum of 7/1 and 3/5.

step 2 Compare the denominators of fractions 7/1 and 3/5 to identify whether it is a like or unlike fraction addition. Since the denominators of given fractions 7/1 and 3/5 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 7/1 and 3/5:
The LCM of 1 and 5 is 5.

step 4 Write the fractions 7/1 and 3/5 in the addition expression form and multiply LCM with all the numerators and denominators of both fractions.
= 7/1 + 3/5
= [(7 x 5)/(1 x 5)] + [(3 x 5)/(5 x 5)]

step 5 Simplify the expression to have common denominator:
= 35/5 + 3/5

step 6 Take the common values out and rewrite the above expression like the below:
= 1/5 x (35/1 + 3/1)
= 1/5 x (35 + 3)

step 7Simplify the above expression further:
= 1/5 x 38
= 38/5
7/1 + 3/5 = 38/5

Hence,
7/1 plus 3/5 as a fraction is 38/5.
