The angular size can be calculated as the diameter of the object (1 inch) divided by the distance to the object (144 inches), which equals approximately 0.0069 radians.
when the size of 1 is the same magnitude size of another with comparable denominators and numbers ; ie, 1/10 = 2/20ths , or 1/4 = 2/8ths, or 4/16ths, because the increase in size between each number set is the same
