Final answer:
The distance between -4.3 and 7.5 on a number line is calculated by taking the absolute difference of the two numbers, resulting in 11.8 units.
Step-by-step explanation:
To find the distance between -4.3 and 7.5 on a number line, you need to calculate the absolute difference between the two numbers. This is done by subtracting the smaller number from the larger number without considering the sign.
The calculation would be:
Distance = |7.5 - (-4.3)|
Distance = |7.5 + 4.3|
Distance = |11.8|
Distance = 11.8 units
So, the distance between -4.3 and 7.5 on a number line is 11.8 units.
