A decimal is a way of writing a number that is not whole. Decimal numbers are 'in-between' numbers. For example, 5.25 is in between the numbers 5 and 6. It is more than 5, but less than 6.
To find out exactly what a decimal number represents, use place value headings, that is tenths, hundredths etc.
The numbers to the left of the decimal point are whole numbers.
The numbers to the right of the decimal point are parts of whole numbers.
