Why can you write 4.7 as 4.70?

Answer 1

You can write 4.7 as 4.70 because the trailing zero after the decimal point does not change the value of the number. Both representations indicate the same quantity, 4.7, but the form 4.70 may be used for consistency, particularly in contexts like financial reporting or measurements, where a specific number of decimal places is required. This practice helps maintain uniformity and clarity in numerical data.
