Natural numbers have to be positive whole numbers such as 10 and 0
Whole numbers are similar, but you can have negative numbers here. You just can't put fractions in there.
The 3rd section is a little odd, Integers don't use fractions or decimals, same as whole numbers. The fractions and decimal numbers would go outside of that section.
Extra note: might be a tricky one because it is in fraction form but it is also written as 3. This means it is a natural number. The reason numbers such as and 0.25 are not natural numbers is because they cannot be put as whole numbers.
