How to Express 0.025 as a Fraction?

To express 0.025 as a fraction, follow these steps:

1. Write down the number as a fraction with 1 as the denominator: \( \frac{0.025}{1} \).
2. Multiply both the numerator and the denominator by 1000 to eliminate the decimal point: \( \frac{0.025 \times 1000}{1 \times 1000} = \frac{25}{1000} \).
3. Simplify the fraction by dividing both the numerator and the denominator by their greatest common divisor (GCD). The GCD of 25 and 1000 is 25: \( \frac{25 \div 25}{1000 \div 25} = \frac{1}{40} \).

Therefore, 0.025 expressed as a fraction is \( \frac{1}{40} \).
