Answer 3

Let's solve these arithmetic expressions:

1. $\frac{1}{2} + \left(-\frac{1}{3}\right)$

To add fractions, we need a common denominator, which in this case is 6. So, we'll convert both fractions to have a denominator of 6:

$\frac{1}{2} = \frac{3}{6}$ (multiplied numerator and denominator by 3)

$-\frac{1}{3} = -\frac{2}{6}$ (multiplied numerator and denominator by 2)

Now, add the fractions:

$\frac{3}{6} + \left(-\frac{2}{6}\right) = \frac{3 - 2}{6} = \frac{1}{6}$

So, $\frac{1}{2} + \left(-\frac{1}{3}\right) = \frac{1}{6}$

2. $-\frac{1}{5} + \frac{3}{5}$

Since both fractions have the same denominator (5), we can directly add the numerators:

$-\frac{1}{5} + \frac{3}{5} = \frac{-1 + 3}{5} = \frac{2}{5}$

So, $-\frac{1}{5} + \frac{3}{5} = \frac{2}{5}$
