To check if Marika's answer is correct, we need to multiply the fractions \( \frac{3}{7} \) and \( \frac{5}{7} \).
The multiplication of two fractions is done by multiplying 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 got \( \frac{15}{7} \), but the correct answer is \( \frac{15}{49} \). Therefore, her answer is incorrect.
