To find the product of the fractions \( \frac{3}{7} \) and \( \frac{5}{7} \), Marika should multiply the numerators together and the denominators together:
\[ \frac{3}{7} \times \frac{5}{7} = \frac{3 \times 5}{7 \times 7} = \frac{15}{49}. \]
Marika's answer of \( \frac{15}{7} \) is incorrect.
The correct response from the options given is:
No, she should have found the product for both the numerators and denominators. The correct answer is \( \frac{15}{49} \).
However, this option is not explicitly provided in your response list. If you meant to check if \( \frac{15}{7} \) was just a random answer, it indeed was incorrect by standard multiplication rules of fractions.
