\(\frac25\) kilogram of soil fills \(\frac13\) of a container. Can 1 kilogram of soil fit in the container? Explain or show your reasoning.

After raining for \(\frac34\) of an hour, a rain gauge is \(\frac25\) filled. If it continues to rain at that rate for 15 more minutes, what fraction of the rain gauge will be filled?

1. To help answer this question, Diego wrote the equation \(\frac34\div \frac25={?}\). Explain why this equation does not represent the situation.
2. Write a multiplication equation and a division equation that do represent the situation.
