Let's Order Rational Numbers

Front

What is a rational number?

Back

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

How do you compare rational numbers?

Back

To compare rational numbers, convert them to a common denominator or decimal form, then determine which is greater or lesser.

Front

What is the absolute value of a number?

Back

The absolute value of a number is its distance from zero on the number line, regardless of direction. For example, the absolute value of -3 is 3.

Front

How do you order rational numbers from least to greatest?

Back

To order rational numbers from least to greatest, compare their values and arrange them in ascending order.

Front

What is the greatest integer less than or equal to a number?

Back

The greatest integer less than or equal to a number is called the floor of that number. For example, the floor of 2.7 is 2.

Front

What is the least integer greater than or equal to a number?

Back

The least integer greater than or equal to a number is called the ceiling of that number. For example, the ceiling of 2.3 is 3.

Front

How do you find the distance between two rational numbers on a number line?

Back

To find the distance between two rational numbers, subtract the smaller number from the larger number and take the absolute value of the result.

Front

What is the difference between positive and negative rational numbers?

Back

Positive rational numbers are greater than zero, while negative rational numbers are less than zero. They are located on opposite sides of zero on the number line.

Front

How can you represent rational numbers on a number line?

Back

Rational numbers can be represented on a number line by marking points that correspond to their values, with equal intervals between them.

Front

What is an integer?

Back

An integer is a whole number that can be positive, negative, or zero. Examples include -3, 0, and 5.
