Express 0.4̄ (0.444...) as a fraction.
- A. 2/5
- B. 4/9
- C. 4/10
- D. 1/4
Answer: B. 4/9
0.4̄ = 4/9. This can be verified: if x = 0.444..., then 10x = 4.444..., so 10x - x = 4, giving 9x = 4, thus x = 4/9.
0.4̄ = 4/9. This can be verified: if x = 0.444..., then 10x = 4.444..., so 10x - x = 4, giving 9x = 4, thus x = 4/9.
Which of the following represents 0.3̄2̄ (0.323232...)?
- A. 32/99
- B. 32/100
- C. 32/90
- D. 3/10
Answer: A. 32/99
For 0.3̄2̄: Let x = 0.3232... Then 100x = 32.3232... So 100x - x = 32, giving 99x = 32, thus x = 32/99.
For 0.3̄2̄: Let x = 0.3232... Then 100x = 32.3232... So 100x - x = 32, giving 99x = 32, thus x = 32/99.
