Answer 1

The given expression is

`(1)/(2)n+(3)/(10)`

Where n = 1/5.

Let's replace the variable for its value.

`(1)/(2)((1)/(5))+(3)/(10)`

First, we solve the product.

`(1)/(10)+(3)/(10)`

Then, we sum fractions. Notice that we just have to sum numerators because the denominators are equal.

`(1+3)/(10)=(4)/(10)=(2)/(5)`

Therefore, the answer is 2/5.
