1. **State the problem:** Leo has $\frac{2}{3}$ cups of flour, which is $\frac{4}{5}$ of the flour needed for 1 batch of dinner rolls. We need to find how many cups of flour Leo needs for 2 batches. 2. **Set up the equation:** Let $x$ be the amount of flour needed for 1 batch. According to the problem: $$\frac{4}{5} \times x = \frac{2}{3}$$ 3. **Solve for $x$:** Multiply both sides by $\frac{5}{4}$ to isolate $x$: $$x = \frac{2}{3} \times \frac{5}{4} = \frac{2 \times 5}{3 \times 4} = \frac{10}{12} = \frac{5}{6}$$ So, Leo needs $\frac{5}{6}$ cups of flour for 1 batch. 4. **Find flour needed for 2 batches:** Multiply the amount for 1 batch by 2: $$2 \times \frac{5}{6} = \frac{10}{6} = \frac{5}{3}$$ **Final answer:** Leo needs $\frac{5}{3}$ cups of flour to make 2 batches of dinner rolls.
