Midpoint of 0.117 and 0.12

Answer 1

Athough the numbers you provided are not points in a 2-dimensional space, they can be considered points on a 1-dimensional number line.

The arithmetic average ( a + b ) ÷ 2 is the midpoint.

By the way, the two numbers are not points in a 3-dimensional space, or any higher level space.

Answer 2

Add them. Divide by 2.

.117 + .12 = .237

.237/2 = .1185

Having shown that, those are not points. Points have coordinates (x,y);
