Tier 3: Rational Numbers on a Number Line

A rational number is any number that can be expressed as the quotient or fraction of two integers, where the denominator is not zero.

Rational numbers can be plotted on a number line by marking their position relative to whole numbers, with fractions and decimals placed between them.

The left side of a number line represents negative numbers.

The right side of a number line represents positive numbers.

$$\frac{5}{4}$$ .

Multiply the whole number by the denominator, add the numerator, and place the result over the original denominator.

0.75.

Look for the position of the number relative to whole numbers and other fractions.

Positive rational numbers are greater than zero, while negative rational numbers are less than zero.

-1.1.
