Answers and reasoning
Reveal the teacher answer key
- 10
10/100 × 100 = 10.
- <
-2 < -6/5; greater numbers lie farther right.
- >
-1 > -4/3; greater numbers lie farther right.
- Diver: 4 m from sea level; bird has greater elevation
|-4| = 4 > |1| = 1, but -4 < 1.
- Diver: 6 m from sea level; bird has greater elevation
|-6| = 6 > |3| = 3, but -6 < 3.
