Given the following question:

`-1,5,(1)/(2),(5)/(7),0,\sqrt[]{2},\sqrt[]{8},-1.27,(76)/(77)`

Natural numbers are positive integers.

5 is a natural number

Whole numbers are integers, neither fraction or decimals just integers.

5, and 0 are whole numbers

Integers are a set of numbers that can be expressed without being a fraction/decimal.

Rational numbers are a set of numbers that can be written as fractions.

-1, 5, 1/2, 5/7, 0, 76/77, 1.27 are all rational numbers they can all be expressed as a fraction.

(zero is also rational)

Irrational numbers cannot be expressed as a fraction

√2, √8,

Real numbers are numbers that include rational and irrational numbers.

-1, 5, 1/2, 5/7, 0, 76/77, -1.27, √2, √8
