Answer 1

To check Marika's answer, we need to multiply the two fractions \( \frac{3}{7} \) and \( \frac{5}{7} \).

We 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 product is \( \frac{15}{49} \).

Therefore, the correct response is:

**No, she should have found the product for both the numerators and denominators. The correct answer is \( \frac{15}{49} \).**
