The most restrict classification of the numbers are given as follows:
- Integer: -15/5 = -3, -1 and -sqrt(49) = -7.
- Rational: 2.123, 3 and 1/4, 0.4 bar(F), square root of 16/25.
- Irrational: π, -sqrt(35).
<h3>Which numbers are natural?</h3>
Natural numbers are positive numbers that do not have a decimal part. Hence among those, the natural numbers is: 23.
<h3>Which numbers are whole?</h3>
Whole numbers are non-negative numbers that do not have a decimal part. Hence among those, the whole number is: 0.
<h3>Which numbers are integers?</h3>
Integers are positive or negative numbers that do not have a decimal part, hence, for this problem, the integer numbers are: -15/5 = -3, -1 and -sqrt(49) = -7.
<h3>Which numbers are rational?</h3>
Fractions and terminating decimal numbers are rational, hence:
2.123, 3 and 1/4, 0.4 bar(F), square root of 16/25.
<h3>Which numbers are irrational?</h3>
Non-terminating and non-repeating decimals, such as non-exact square roots.
Hence the irrational numbers are:
π, -sqrt(35).
