1. **State the problem:** Jordan used a fraction of pints of blue paint represented as $\frac{\square}{\square}$. We are given one part of the fraction as $\frac{1}{4}$. We need to understand what this fraction means and how to interpret it. 2. **Understanding fractions:** A fraction $\frac{a}{b}$ means $a$ parts out of $b$ equal parts. Here, $\frac{1}{4}$ means 1 part out of 4 equal parts. 3. **Interpreting the problem:** Jordan used $\frac{1}{4}$ pints of blue paint. This means if the total paint is divided into 4 equal parts, Jordan used 1 of those parts. 4. **No further calculation needed:** Since the fraction is already given as $\frac{1}{4}$, the amount of blue paint Jordan used is exactly $\frac{1}{4}$ pints. 5. **Check your work:** On Zearn or any other platform, verify that $\frac{1}{4}$ is correctly understood as one quarter of a pint. **Final answer:** Jordan used $\frac{1}{4}$ pints of blue paint.
