1. The problem asks to convert the mixed number 1 1/4 cups into an improper fraction. 2. A mixed number consists of a whole number and a fraction. To convert it to an improper fraction, use the formula: $$\text{Improper fraction} = \frac{(\text{whole number} \times \text{denominator}) + \text{numerator}}{\text{denominator}}$$ 3. For 1 1/4, the whole number is 1, the numerator is 1, and the denominator is 4. 4. Substitute these values into the formula: $$\frac{(1 \times 4) + 1}{4} = \frac{4 + 1}{4}$$ 5. Simplify the numerator: $$\frac{5}{4}$$ 6. Therefore, 1 1/4 cups written as an improper fraction is $\frac{5}{4}$ cups. This fraction is greater than one, as required.
