A recipe requires \( \frac{3}{4} \) of a cup of milk for every \( 1 \frac{1}{2} \) cups of flour. What is the ratio of cups of milk to one cup of flour? Enter your answer as a whole number, proper fraction, or mixed number in simplest form.

To find the ratio of cups of milk to one cup of flour, we first need to establish the relationship given in the recipe: - Milk: \( \frac{3}{4} \) cup - Flour: \( 1 \frac{1}{2} \) cups, which is equivalent to \( \frac{3}{2} \) cups of flour. Now, we can set up the ratio: \[ \text{Ratio} = \frac{\text{Milk}}{\text{Flour}} = \frac{\frac{3}{4}}{\frac{3}{2}}. \] Dividing by a fraction is the same as multiplying by its reciprocal: \[ \frac{3}{4} \times \frac{2}{3} = \frac{3 \times 2}{4 \times 3} = \frac{6}{12} = \frac{1}{2}. \] So, the ratio of cups of milk to one cup of flour is \( \frac{1}{2} \).
