Convert the fraction \frac{7}{8} to a decimal and round it to the nearest hundredth.
Answer
0.88
The correct answer is 0.88 — Final answer: 0.88.
Step-by-step solution
- Perform long division of 7 by 8.
- 8 goes into 7 zero times → integer part 0; bring down a decimal point and a zero to get 70.
- 8 goes into 70 eight times (8\times8=64) leaving remainder 6 → first decimal digit 8.
- Multiply remainder 6 by 10 → 60; 8 goes into 60 seven times (8\times7=56) leaving remainder 4 → second decimal digit 7.
- Continue division: 4\times10=40; 8 goes into 40 five times remainder 0 → third decimal digit 5 (and division ends).
- The decimal representation is 0.875. Since the third decimal digit is 5, round up the second decimal digit 7 to 8.
- Thus 0.875 rounded to the nearest hundredth is 0.88.
- Final answer: 0.88.
