  • Common fraction: 1/2
  • Decimal: 0.5
  • Percentage: 50%

Now let us have a closer look at the common fraction:

2 Numerator — Shows how many parts are in the fraction
the vinculum is the symbol for “divide by”
5 Denominator — Shows how many equal parts are in the whole object


Remember: The denominator can never be zero because you cannot divide by zero.
