Problem
A recipe calls for \( 2 \frac{1}{3} \) cups of flour. Jane needs to make only half of the recipe. Which expression could Jane use to calculate the number of cups of flour she needs? A. \( 2 \frac{1}{3}+\frac{1}{2} \) B. \( 2 \frac{1}{3}-\frac{1}{2} \) C. \( 2 \frac{1}{3} \cdot \frac{1}{2} \) D. \( 2 \frac{1}{3} \div \frac{1}{2} \)
Solution
Step 1 ：Convert \( 2 \frac{1}{3} \) to an improper fraction: \( \frac{7}{3} \)
Step 2 ：Multiply by \( \frac{1}{2} \): \( \frac{7}{3} \cdot \frac{1}{2} \)
Step 3 ：Simplify the expression: \( \frac{7}{6} \)
