How do i solve for the distance between numbers on a number line using additive inverse

You owuld have to count the difference between the numbers.

Step-by-step explanation:

to find the distance between 1 to ten:

1_|__|_|_|__|__|__|__|_10

The addititive inverse would be 9 since there are nine lines before it gets to ten. So the distance between 1 and 10 would be 9.

(Sorry if this doesn't make sense, comment and I'll try to explain any other questions)

ratio is 2 : 9

the answer is three

13.5 : 3
