find the distance between 7.5 and -3.1
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.
In this case, the larger number is 7.5 and the smaller number is -3.1.
Distance = |7.5 - (-3.1)|
Distance = |7.5 + 3.1|
Distance = |10.6|
Distance = 10.6
So, the distance between 7.5 and -3.1 is 10.6 units.
