Answer 2

Let's solve the given expression step by step.

First, we deal with the division of the mixed number (1 2/5) by 2:

1 2/5 is equivalent to (7/5) in improper fraction form. So, (1 2/5) divided by 2 is:

(7/5) : 2 = (7/5) * (1/2) = 7/10.

Next, we add 1 and -1/2:

1 + (-1/2) = 1 - 1/2 = 2/2 - 1/2 = 1/2.

So, putting it all together:

(1 2/5) : 2 + (1 + (-1/2)) = 7/10 + 1/2.

To add these fractions, we need a common denominator, which is 10 in this case:

7/10 + 5/10 = 12/10 = 6/5.

So, the final result is 6/5.
