Exercise 28 Page 7

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|

Practice makes perfect

We want to complete the given statement. To do so, we will evaluate the absolute values on both sides.

2 |- 5|

The absolute value of a number is the distance between this number and 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.
absolute value
With this in mind, let's simplify the right-hand side! ccc |- 5|= 5 We will plot the numbers on a number line to see which one is greater.
plotting point
We can see that 2 is located to the left of |- 5|. This means it is less than |- 5|. With this in mind, we can complete our statement.

2 < |- 5|
