Step-by-step explanation: The set of counting numbers {1, 2, 3, 4, ...} is called the set of natural numbers. The natural numbers begin with 1 and go on indefinitely.

Decimals are not natural numbers unless they have a 0 after the decimal point that repeats. However, 2.8 does not so it's not natural.
