Let A = 1/2 and B = 3/4 on a number line, and let C be a point such that B is exactly the midpoint of A and C. What fraction does C represent?

Question

Accepted Answer

1. If B is the midpoint of A and C, then C = 2B - A = 2(3/4) - 1/2 = 3/2 - 1/2 = 1. So C is the point 1.

Let A $= \frac{1}{2}$ and B $= \frac{3}{4}$ on a number line, and let C be a point such that B is exactly the midpoint of A and C.
