- 3/4, 2/3, 5/6
- 5/6, 3/4, 2/3
- 2/3, 5/6, 3/4
Correct answer: 2/3, 3/4, 5/6
Converting to decimals: 2/3 ≈ 0.667, 3/4 = 0.75, 5/6 ≈ 0.833 — so the order is 2/3 < 3/4 < 5/6.
Question 5: Which U.S. region is most known for the Great Plains and large-scale wheat farming?

- 2.5 g/cm³ (Correct answer)
- 0.4 g/cm³
- 25 g/cm³
- 350 g/cm³
Correct answer: 2.5 g/cm³
Density = mass ÷ volume = 250 ÷ 100 = 2.5 g/cm³.
Question 7: Which word is an antonym of 'benevolent'?
- Generous
- Kind
- Malicious (Correct answer)
