Learn how to find what is 2/5 plus 2/15 in fraction form just in a few minutes. We have covered the easiest method to write 2/5 + 2/15 as a fraction and decimal.

Summary: 2/5 plus 2/15 = 8/15
Since both fractions have unequal denominators, 2/5 plus 2/15 is an unlike fractions addition. For adding unlike fractions, you have to first find the equivalent fractions for fraction 2/5 and fraction 2/15 in order to have the same denominators for both fractions. Therefore, you have to find the LCM of denominators 5 and 15. 15 is the LCM of 5 and 15. Multiplying the LCM 15 with the numerators and denominators of both fractions (2/5 x 15/15) + (2/15 x 15/15), and simplify further in order to have the common denominator. So the equivalent fraction for 2/5 is 6/15 and for 2/15 is 2/15. By simplifying this fraction addition 6/15 + 2/15, it becomes 8/15.

2. Cross multiplication method.

(2/5) + (2/15) using LCM Method:
What is 2/5 plus 2/15 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 2/5
Fraction B: 2/15

What to be found?
(2/5) + (2/15) = ?
Find what's the sum of 2/5 and 2/15.

step 2 Compare the denominators of fractions 2/5 and 2/15 to identify whether it is a like or unlike fraction addition. Since the denominators of given fractions 2/5 and 2/15 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 2/5 and 2/15:
The LCM of 5 and 15 is 15.

step 4 Write the fractions 2/5 and 2/15 in the addition expression form and multiply LCM with all the numerators and denominators of both fractions.
= 2/5 + 2/15
= [(2 x 15)/(5 x 15)] + [(2 x 15)/(15 x 15)]

step 5 Simplify the expression to have common denominator:
= 6/15 + 2/15

step 6 Take the common values out and rewrite the above expression like the below:
= 1/15 x (6/1 + 2/1)
= 1/15 x (6 + 2)

step 7Simplify the above expression further:
= 1/15 x 8
= 8/15
2/5 + 2/15 = 8/15

Hence,
2/5 plus 2/15 as a fraction is 8/15.
