1. The first problem asks which expression is equivalent to $\frac{3}{5}$. 2. The fraction $\frac{3}{5}$ means 3 divided by 5, so the equivalent expression is $3 \div 5$. 3. Checking the options: - a. $3 \times 5 = 15$, not equivalent. - b. $3 + 5 = 8$, not equivalent. - c. $3 \div 5 = \frac{3}{5}$, equivalent. - d. $3 - 5 = -2$, not equivalent. 4. Therefore, the correct answer is c. $3 \div 5$. This completes the solution for the first question.
