## How to Convert a Decimal to a Fraction

### Method

1. Write the decimal as a fraction over a power of 10 (e.g., 0.75 = 75/100)
2. Find the GCD (greatest common divisor) of the numerator and denominator
3. Divide both by the GCD to simplify

For example, 0.75 = 750/1000. GCD(750, 1000) = 250. So 750/1000 = 3/4.

计算示例

Convert 0.75 to a fraction.

  1. 0.75 = 750/1000
  2. GCD(750, 1000) = 250
  3. 750 / 250 = 3
  4. 1000 / 250 = 4
  5. 0.75 = 3/4
