Decimal Numbers (KS3 Definition):
A decimal number is a number that includes a decimal point, which separates whole numbers from fractions of a whole. The numbers to the left of the decimal point are whole numbers, and the numbers to the right represent parts of a whole (tenths, hundredths, thousandths, etc.).
For example, in 4.56:
4 is the whole number part.
5 is in the tenths place (5/10).
6 is in the hundredths place (6/100).
Decimals are used in money (£2.50), measurements (3.75 cm), and many everyday calculations
