Definition
A decimal is a way of writing numbers that are not whole, using a decimal point to separate the whole part from the fractional part.
A decimal is another way to write a fraction. Instead of saying "one half," you write 0.5. The digits after the decimal point show parts smaller than one.
Examples
- 0.5 is the same as 1/2.
- 3.25 means 3 and 25 hundredths.
- 0.1 is the same as 1/10.
