5/2 + 3/10 as a fraction

Learn how to find what is 5/2 plus 3/10 in fraction form just in a few minutes. We have covered the easiest method to write 5/2 + 3/10 as a fraction and decimal.

Summary: 5/2 plus 3/10 = 14/5
Since both fractions have unequal denominators, 5/2 plus 3/10 is an unlike fractions addition. For adding unlike fractions, you have to first find the equivalent fractions for fraction 5/2 and fraction 3/10 in order to have the same denominators for both fractions. Therefore, you have to find the LCM of denominators 2 and 10. 10 is the LCM of 2 and 10. Multiplying the LCM 10 with the numerators and denominators of both fractions (5/2 x 10/10) + (3/10 x 10/10), and simplify further in order to have the common denominator. So the equivalent fraction for 5/2 is 25/10 and for 3/10 is 3/10. By simplifying this fraction addition 25/10 + 3/10, it becomes 28/10.

The below workout with step by step calculation shows how to find the equivalent fraction between 5/2 and 3/10 by adding two fractions with different, unequal or unlike denominators. The sum in fraction form for 5/2 plus 3/10 can be obtained by using anyone of the two methods below.
1. LCM method
2. Cross multiplication method.

(5/2) + (3/10) using LCM Method:
What is 5/2 plus 3/10 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 5/2
Fraction B: 3/10

What to be found?
(5/2) + (3/10) = ?
Find what's the sum of 5/2 and 3/10.

step 2 Compare the denominators of fractions 5/2 and 3/10 to identify whether it is a like or unlike fraction addition. Since the denominators of given fractions 5/2 and 3/10 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 5/2 and 3/10:
The LCM of 2 and 10 is 10.

step 4 Write the fractions 5/2 and 3/10 in the addition expression form and multiply LCM with all the numerators and denominators of both fractions.
= 5/2 + 3/10
= [(5 x 10)/(2 x 10)] + [(3 x 10)/(10 x 10)]

step 5 Simplify the expression to have common denominator:
= 25/10 + 3/10

step 6 Take the common values out and rewrite the above expression like the below:
= 1/10 x (25/1 + 3/1)
= 1/10 x (25 + 3)

step 7Simplify the above expression further:
= 1/10 x 28
= 28/10
= 14/5
5/2 + 3/10 = 14/5

Hence,
5/2 plus 3/10 as a fraction is 14/5.
