\]
Answer: 24
Problem 2: $\frac{5}{7}$ of 70
\[
\frac{5}{7} \times 70 = \frac{5 \times 70}{7} = \frac{350}{7} = 50
\]
Answer: 50
Problem 3: $\frac{4}{5}$ of 45
\[
\frac{4}{5} \times 45 = \frac{4 \times 45}{5} = \frac{180}{5} = 36
\]
Answer: 36
Problem 4: $\frac{3}{8}$ of 72
\[
\frac{3}{8} \times 72 = \frac{3 \times 72}{8} = \frac{216}{8} = 27
\]
Answer: 27
Problem 5: $\frac{2}{7}$ of 28
\[
