1. **State the problem:** Jay's cookie recipe requires 3 cups of chocolate chips for every 4 cups of flour. He wants to make a smaller batch using only 1 cup of flour. We need to find how many cups of chocolate chips he should use. 2. **Write the ratio and formula:** The ratio of chocolate chips to flour is given as $$\frac{3}{4}$$. 3. **Set up a proportion:** Let $x$ be the number of cups of chocolate chips Jay should use for 1 cup of flour. $$\frac{3}{4} = \frac{x}{1}$$ 4. **Solve for $x$:** Multiply both sides by 1 to isolate $x$: $$x = \frac{3}{4} \times 1$$ 5. **Simplify:** $$x = \frac{3}{4}$$ 6. **Interpret the result:** Jay should use $\frac{3}{4}$ cups of chocolate chips when using 1 cup of flour. **Final answer:** $$\boxed{\frac{3}{4} \text{ cups of chocolate chips}}$$
