Read the numbers properly. Remember to use "and" after hundreds (e.g., 3 456 → three thousand, four hundred and fifty six).
Note: Thousands and millions are separated only by spaces (e.g., 7 403 126).
Decimal fractions are said with each figure separate. We use a full stop (called "point"), not a comma.
Example: 3.375 → three point three seven five.
