What is 3/10 plus 1/5 as a fraction?

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

What to be found?
3/10+1/5 = ?
Find what's the sum of 3/10 and 1/5.

step 2 Compare the denominators of fractions 3/10 and 1/5 to identify whether it is a like or unlike fraction addition. Since the denominators of given fractions 3/10 and 1/5 are not equal, it is said to be unlike fractions addition.

The LCM of 10 and 5 is 10.

step 4 Write the fractions 3/10 and 1/5 in the addition expression form and multiply LCM with all the numerators and denominators of both fractions.
=3/10+1/5
=(3 x 10)/(10 x 10)+(1 x 10)/(5 x 10)

step 5 Simplify the expression to have common denominator:
=3/10+2/10

step 6 Take the common values out and rewrite the above expression like the below:
=1/10 x (3/1+2/1)
=1/10 x (3 + 2)

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

Hence,
3/10 plus 1/5 equals to 1/2 in fraction.
