Answer 2

Answer:

Rational number

A rational number (Q) is any number which can be written as:

ab

where a and b are integers and b≠0.

The following numbers are all rational numbers:

101;217;−1−3;1020;−36

We see that all numerators and all denominators are integers.

This means that all integers are rational numbers, because they can be written with a denominator of 1.

Irrational numbers

Irrational numbers (Q′) are numbers that cannot be written as a fraction with the numerator and denominator as integers.

Examples of irrational numbers:

2–√;3–√;4–√3;π;1+5–√2

These are not rational numbers, because either the numerator or the denominator is not an integer.

Decimal numbers (EMA5)

All integers and fractions with integer numerators and non-zero integer denominators are rational numbers. Remember that when the denominator of a fraction is zero then the fraction is undefined.

You can write any rational number as a decimal number but not all decimal numbers are rational numbers. These types of decimal numbers are rational numbers:

Decimal numbers that end (or terminate). For example, the fraction 410 can be written as 0,
