1. Lesson 2-2 Example 4 2-2 Solve. CHEMISTRY For her science project, Katherine used four different liquids to make one new solution. In order for her experiment to go well, she must label each container with the percent of liquid with which it was filled. How should she mark the containers? UnderstandRead the problem. Write what you know. The containers must be marked with a percent.

2. Lesson 2-2 Example 4 2-2 PlanPick a strategy. Two strategies are to look for a pattern and use logical reasoning.

3. Lesson 2-2 Example 4 2-2 SolveLook at the first container. How full is it? Completely full How does the second container compare to the first one? Half full How does the third container compare with the second one? Half as full as the second container

4. Lesson 2-2 Example 4 2-2 How does the fourth container compare with the other three containers? More than half full but not completely full Label each container with the correct percent, fraction, and decimal.

5. Lesson 2-2 Example 4 2-2 Decimal1.0,0.50,0.25,0.75 Percent100%50%25%75% Fraction

6. Lesson 2-2 Example 4 2-2 CheckIs the greatest percent under the container with the largest amount of liquid? Is the least percent under the beaker with the least amount of liquid?
