Round 4.5 to 1 decimal place.
- 4.5

ProCompare and infer.
Complete: 0.75 = ___ / 100 = ___ / 4.
- 75 and 3
- 7.5 and 3
- 75 and 4
- 75 and 25
Answer: 75 and 3. 0.75 = 75/100 = 3/4.
GuruMulti-step reasoning.
A teacher marks 0.5 = 1/2 as wrong. Is the teacher right? Why?
- No — the teacher is wrong. 0.5 = 5/10 = 1/2. They're equal.
- Yes — 0.5 ≠ 1/2.
- Cannot tell.
- Yes — 0.5 = 1/5.
Answer: No — the teacher is wrong. 0.5 = 5/10 = 1/2. They're equal.. 0.5 = 5/10 = 1/2.
