What is five as a decimal?

Answer 1

"5" is already a decimal number. You could also write it as "5.0". A decimal is a whole number in the decimal (base-10) number system or a proper fraction whose denominator is a power of 10. Decimal numbers are written by convention with the whole-number part to the left of a "decimal point" (.) and the fractional part to the right. Either or both the whole or fractional part may be zero (0).
