1. **Problem 8:** Determine which fractions make $200 \times \text{fraction} > 200$.
2. **Rule:** For $200 \times x > 200$, we need $x > 1$.
3. Check each fraction:
- A: $\frac{1}{4} = 0.25 < 1$ (No)
- B: $1 \frac{1}{4} = 1 + \frac{1}{4} = 1.25 > 1$ (Yes)
- C: $\frac{7}{8} = 0.875 < 1$ (No)
- D: $\frac{5}{3} = 1.666... > 1$ (Yes)
4. **Answer for 8:** B and D.

5. **Problem 9:** Simplify $\frac{7}{8} \div \frac{3}{4}$.
6. **Formula:** Division of fractions: $\frac{a}{b} \div \frac{c}{d} = \frac{a}{b} \times \frac{d}{c}$.
7. Apply formula:
$$\frac{7}{8} \div \frac{3}{4} = \frac{7}{8} \times \frac{4}{3}$$
8. Multiply numerators and denominators:
$$= \frac{7 \times 4}{8 \times 3} = \frac{28}{24}$$
9. Simplify fraction:
$$\frac{28}{24} = \frac{\cancel{28}^{7 \times 4}}{\cancel{24}^{6 \times 4}} = \frac{7}{6}$$
10. **Answer for 9:** $\frac{7}{6}$.

11. **Problem 10:** Find weight of water in aquarium.
12. Given: 1 gallon weighs 7.2 pounds, tank holds 11.4 gallons.
13. Multiply gallons by weight per gallon:
$$11.4 \times 7.2 = 82.08$$
14. **Answer for 10:** 82.08 pounds.

15. **Problem 11:** Order plant growth amounts from least to greatest.
16. Given:
- Kyla: 0.68 inch
- Connor: $\frac{1}{2} = 0.5$ inch
- Lucy: 0.55 inch
- Maggie: $\frac{2}{3} \approx 0.6667$ inch
17. Order numerically:
$$0.5 < 0.55 < 0.6667 < 0.68$$
18. Corresponding names:
Connor (0.5), Lucy (0.55), Maggie (0.6667), Kyla (0.68)
19. **Answer for 11:** Connor, Lucy, Maggie, Kyla.

20. **Problem 12:** How many times can Maggie feed her cow?
21. Given: Total feed = 21.25 pounds, feed per time = $1 \frac{1}{4} = 1.25$ pounds.
22. Divide total feed by feed per time:
$$\frac{21.25}{1.25}$$
23. Simplify division:
$$\frac{21.25}{1.25} = 17$$
24. **Answer for 12:** 17 times.
