Answer 3

Let's solve these arithmetic problems step by step:

1. $2 \frac{1}{15} + \frac{3}{5}$ To add these fractions, we need to have a common denominator, which is 15 in this case. $2 \frac{1}{15} = \frac{30}{15} + \frac{1}{15} = \frac{31}{15}$ Now, add $\frac{31}{15} + \frac{3}{5}$: $\frac{31}{15} + \frac{3}{5} = \frac{31}{15} + \frac{9}{15} = \frac{31 + 9}{15} = \frac{40}{15} = \frac{8}{3}$

So, $2 \frac{1}{15} + \frac{3}{5} = \frac{8}{3}$.

2. $5 - 1 \frac{3}{5}$ To subtract mixed numbers, subtract the whole numbers and the fractions separately: $5 - 1 = 4$ $\frac{3}{5}$ So, $5 - 1 \frac{3}{5} = 4 \frac{3}{5}$.

3. $3 \frac{1}{6} - 1 \frac{1}{3}$ To subtract mixed numbers, subtract the whole numbers and the fractions separately: $3 - 1 = 2$ $\frac{1}{6} - \frac{1}{3}$ To subtract the fractions, find a common denominator, which is 6 in this case: $\frac{1}{6} - \frac{1}{3} = \frac{1}{6} - \frac{2}{6} = -\frac{1}{6}$

So, $3 \frac{1}{6} - 1 \frac{1}{3} = 2 - \frac{1}{6} = 1 \frac{5}{6}$.

4. $1 \frac{1}{3} - \frac{1}{2}$ To subtract mixed numbers, subtract the whole numbers and the fractions separately: $1 - 1 = 0$ $\frac{1}{3} - \frac{1}{2}$ To subtract the fractions, find a common denominator, which is 6 in this case: $\frac{1}{3} - \frac{1}{2} = \frac{2}{6} - \frac{3}{6} = -\frac{1}{6}$

So, $1 \frac{1}{3} - \frac{1}{2} = 0 - \frac{1}{6} = -\frac{1}{6}$
