After raining for LaTeX: \frac{3}{4}3 4 of an hour, a rain gauge is LaTeX: \frac{2}{5}2 5 filled. If it continues to rain at that rate for 15 more minutes, what fraction of the rain gauge will be filled? To help answer this question, Diego wrote the division equation LaTeX: \frac{3}{4}\div\frac{2}{5}=?3 4 ÷ 2 5 = ?. Explain why this equation does not represent the situation.
