Conversion: Fraction - Decimal

Conversion: Fraction - Decimal

1. To convert a fraction to a decimal, divide the numerator by the denominator.

   • If the result ends (for example, 1/4 = 0.25), it is an exact decimal.
   • If the result repeats (example., 1/3 = 0.333...), it is a repeating decimal.

2. To convert a decimal to a fraction:

   • If it is an exact decimal, write it over 10, 100, 1000, depending on the number of decimal places, and then simplify.
     • If it is a repeating decimal, it is equated to a variable (x), multiplied to move the period, the equations are subtracted, and the fraction is solved. Then it is simplified.
