Question

1. level 3 (complex): a recipe for 4 people calls for 2 1/4 cups of flour. if you want to make enough for 10 people, how much flour do you need? express your answer as a decimal.

Explanation:

Step1: Convert mixed number to decimal

First, convert \(2\frac{1}{4}\) to a decimal. We know that \(\frac{1}{4}=0.25\), so \(2\frac{1}{4} = 2 + 0.25=2.25\) cups for 4 people.

Step2: Find flour per person

To find the amount of flour per person, divide the total flour for 4 people by 4. So, per person flour is \(\frac{2.25}{4}=0.5625\) cups.

Step3: Calculate flour for 10 people

Now, to find the flour needed for 10 people, multiply the per - person flour by 10. So, \(0.5625\times10 = 5.625\) cups.

Answer:

\(5.625\)
