if I'm 2 lessons into a class and my progress bar says that I am 1/3 of the way complete. How many lessons are in the class?

Well you have 6 lessons in total.

Step-by-step explanation:

if you finished 2 lessons you are 1/3

It is basically the same as 2/6 lessons

so

2/6 = 1/3

You have 6 lessons

3/6 chance

step-by-step explanation:

half of the nubers are odd numbers (1,3,5) which in that case if you would be told to simplify it would be 1/2

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
