Exercise 9 Page 406

The absolute value of a number is its distance from 0 on the number line. Since distance is always greater than or equal to 0, the absolute value of any number is greater than or equal to 0.

2.5 = |2.5|

The absolute value of a number is its distance from 0 on the number line. Since distance is always greater than or equal to 0, the absolute value of any number is greater than or equal to 0. The absolute value of a non-negative number is equal to the number, while the absolute value of a negative number is equal to its opposite.

Now we want to complete the given statement using one of the inequality signs or an equal sign.

2.5 |2.5| Since 2.5 is a positive number, its absolute value is the number itself. |2.5|= 2.5 We can see that we have to complete the statement with an equality sign. Let’s illustrate this with a picture!

Since |2.5| equals 2.5, we complete the statement with an equality sign. 2.5 = |2.5|
