The correct answer is: $\frac{7}{8}$
Explanation
We convert the decimal to a fraction by writing it over a power of 10 and then simplifying.
Steps:
- Write the decimal as a fraction: $0.875=\frac{875}{1000}$
- Divide numerator and denominator by their greatest common divisor $125$: $$\frac{875}{1000}=\frac{875\div125}{1000\div125}=\frac{7}{8}$$
- Final simplified fraction: $\frac{7}{8}$
Therefore, $0.875=\frac{7}{8}$.
