Those images aren't good enough, I can't really get a good look. Basically, if there are nine little lines between each whole number, then each little line represents a tenth of a whole number, or 0.1. If there are four little lines between each whole number, then each little lines is 0.2. So, you just count up from the whole number below the value. For A, start at 1.0 and count up, each little line is 0.1 (if there are nine lines between each whole number), and figure out where A lies. Hope it helped, wish I could give a definite answer.
