What is 3 1/7 as a decimal?
Answer
Fraction 3 1/7 as a decimal is
3.142857
≈ 3.14 to hundredths
Repeating decimal: denominator 7 has the factor 7, not 2 or 5 · the bar marks the period 142857 — 6 digits repeat forever
3 1/7: whole part, then 1 ÷ 7
Whole part 3 stays in front; divide the fraction part:
| remainder | ×10 | = digit × 7 + new remainder | digit |
|---|---|---|---|
| 1 | 10 | 1 × 7 + 3 | 1 |
| 3 | 30 | 4 × 7 + 2 | 4 |
| 2 | 20 | 2 × 7 + 6 | 2 |
| 6 | 60 | 8 × 7 + 4 | 8 |
| 4 | 40 | 5 × 7 + 5 | 5 |
| 5 | 50 | 7 × 7 + 1 | 7 |
Remainder 1 is back after the 6th division → the 6 digits 142857 repeat: 0.142857.
3 + 0.142857 = 3.142857
