## Problem by problem

- **1.** Not yet: you wrote "2/6", answer 3/4. You added the tops and the bottoms. Make the bottoms match first: 1/2 is 2/4. 1/2 = 2/4, and 2/4 + 1/4 = 3/4.
- **2.** Right: you wrote "5/6". Correct.
- **3.** Right: you wrote "2 1/4 cups". Correct.
- **4.** Right: you wrote "9". Correct.
- **5.** Not yet: you wrote "15", answer 45. 15 is the discount. The sale price is what is left: 60 - 15. 25% of 60 is 15, and 60 - 15 = 45.
- **6.** Right: you wrote "60%". Correct.
- **7.** Not yet: you wrote "125/1000", answer 1/8. That is equal, but not in lowest terms. Divide top and bottom by 125. 0.125 = 125/1000 = 1/8.
- **8.** Right: you wrote "0.4". Correct.
