### Instruction: A recipe calls for $4 \frac{1}{2}$ cups of flour. If you only make half of the recipe, then how many cups of flour do you need? Express your answer as a mixed number.### Response: We just need to divide 4 1/2 by 2.
Right. So 4 1/2 = 9/2.
And 9/2 divided by 2 is 9/2 * 1/2.
Which equals 9/4.
