Nine points are evenly spaced on a standard number line. They are labeled A through I, from left to right. The coordinates of points A and I are 1 and 10, respectively. What is the coordinate of point B? Express your answer as a decimal to the nearest thousandth.

Nine points have eight gaps.   Hence A to B is a distance of (10 - 1)/8  = 9/8.

 

Coordinate of B  = coordinate of A + 9/8

 

I'll let you finish.
