Convert 0.625 to a fraction.

Explanation:
When a terminating decimal is written as a fraction, you can place the digits over a power of 10 and then simplify. Since 0.625 has three digits after the decimal, write it as 625/1000. Both numbers share a greatest common divisor of 125, so divide numerator and denominator by 125 to get 625/1000 = 5/8. This fraction equals 0.625, so it matches the decimal exactly. The other fractions correspond to decimals 0.6, 0.875, and 0.8125, which are not equal to 0.625.
