To find the distance between two numbers on a number line, you subtract the smaller number from the larger number and take the absolute value of the result.
Given the numbers 18.25 and -7.4, we can calculate the distance as follows:
-
Subtract the smaller number from the larger number: \[ 18.25 - (-7.4) = 18.25 + 7.4 = 25.65 \]
-
The distance between 18.25 and -7.4 is: \[ |18.25 - (-7.4)| = |18.25 + 7.4| = |25.65| = 25.65 \]
Thus, the distance between 18.25 and -7.4 on the number line is 25.65.
