Let's break down the problems step by step from the image you uploaded:

Problem 3:

$4 - \frac{8}{5} + \frac{4}{5}$ To solve:

• First, subtract $\frac{8}{5}$ from 4. Convert 4 to a fraction: $\frac{20}{5} - \frac{8}{5} = \frac{12}{5}$.
• Now, add $\frac{4}{5}$: $\frac{12}{5} + \frac{4}{5} = \frac{16}{5}$ Thus, the answer is $\frac{16}{5}$ or $3 \frac{1}{5}$.

Problem 4:

$5 - 4 + \frac{4}{3} + 2$ To solve:

• First, simplify the integers: $5 - 4 + 2 = 3$.
• Now, add $\frac{4}{3}$ to 3. Convert 3 to a fraction: $\frac{9}{3} + \frac{4}{3} = \frac{13}{3}$. Thus, the answer is $\frac{13}{3}$ or $4 \frac{1}{3}$.

Problem 5:

$42 \div 7 + \frac{1}{5}$ To solve:

• First, divide 42 by 7: $42 \div 7 = 6$.
• Now, add $\frac{1}{5}$ to 6: $6 + \frac{1}{5} = \frac{30}{5} + \frac{1}{5} = \frac{31}{5}$. Thus, the answer is $\frac{31}{5}$ or $6 \frac{1}{5}$.

Problem 6:

$2 - \frac{2}{9} \times 7$ To solve:

• First, multiply $\frac{2}{9}$ by 7: $\frac{2}{9} \times 7 = \frac{14}{9}$.
• Now, subtract $\frac{14}{9}$ from 2. Convert 2 to a fraction: $\frac{18}{9} - \frac{14}{9} = \frac{4}{9}$. Thus, the answer is $\frac{4}{9}$.

Problem 7:

$4 + \frac{2}{3} - 3 + \frac{1}{2}$ To solve:

• First, simplify the integers: $4 - 3 = 1$.
• Now, add the fractions: $1 + \frac{2}{3} + \frac{1}{2}.$ Find a common denominator for $\frac{2}{3}$ and $\frac{1}{2}$, which is 6: $\frac{2}{3} = \frac{4}{6}, \quad \frac{1}{2} = \frac{3}{6}.$ Now, add: $\frac{4}{6} + \frac{3}{6} = \frac{7}{6}.$ Thus, $1 + \frac{7}{6} = \frac{13}{6}$ or $2 \frac{1}{6}$.

Problem 8:

$6 \div \frac{3}{5} - \frac{2}{5} \times 4$ To solve:

• First, divide 6 by $\frac{3}{5}$. Dividing by a fraction is equivalent to multiplying by the reciprocal: $6 \div \frac{3}{5} = 6 \times \frac{5}{3} = \frac{30}{3} = 10.$
• Now, multiply $\frac{2}{5} \times 4 = \frac{8}{5}$.
• Finally, subtract: $10 - \frac{8}{5} = \frac{50}{5} - \frac{8}{5} = \frac{42}{5}$. Thus, the answer is $\frac{42}{5}$ or $8 \frac{2}{5}$.

Problem 9:

$3 + 4 \div \frac{1}{8}$ To solve:

• First, divide 4 by $\frac{1}{8}$. Dividing by $\frac{1}{8}$ is the same as multiplying by 8: $4 \div \frac{1}{8} = 4 \times 8 = 32.$
• Now, add: $3 + 32 = 35$. Thus, the answer is 35.

Problem 10:

$8 \times 3 - \frac{7}{2}$ To solve:

• First, multiply 8 by 3: $8 \times 3 = 24$.
• Now, subtract $\frac{7}{2}$ from 24. Convert 24 to a fraction: $\frac{48}{2} - \frac{7}{2} = \frac{41}{2}.$ Thus, the answer is $\frac{41}{2}$ or $20 \frac{1}{2}$.
