1. **Problem Statement:** How many scoops of 1/3 cup are needed to measure 1.5 cups of sugar? 2. **Formula and Explanation:** To find the number of scoops, divide the total amount of sugar needed by the size of one scoop: $$\text{Number of scoops} = \frac{\text{Total cups needed}}{\text{Size of one scoop}}$$ 3. **Convert 1/3 cup to decimal:** $$\frac{1}{3} = 0.333... \approx 0.3$$ 4. **Calculate the number of scoops:** $$\frac{1.5}{0.3}$$ 5. **Show intermediate cancellation:** $$\frac{\cancel{1.5}}{\cancel{0.3}} = 5$$ (Note: Actually, 1.5 divided by 0.3 equals 5, not 4.5 as in the user's note.) 6. **Answer:** You need 5 scoops of 1/3 cup to measure 1.5 cups of sugar. This means you fill the 1/3 cup scoop 5 times to get the required 1.5 cups.
