b. \( 6 \div \frac{1}{3}= \)

When you divide by a fraction, it's the same as multiplying by its reciprocal! So for \( 6 \div \frac{1}{3} \), you can flip \( \frac{1}{3} \) to become \( 3 \) and multiply. That gives you \( 6 \times 3 = 18 \). Easy peasy! To visualize it, picture having 6 whole pizzas and you want to share them with friends, where each friend gets a third of a pizza. You’d find you can actually serve up 18 slices! So, dividing by a fraction can feel like a pizza party waiting to happen!
