    Why is this and other lessons taught as if someone already know the answers he says 0.05 = 1/20 but never states why or how he comes to do the math to get to that equation / answer..If i knew how to to the steps already to get the answers i would not be on here trying to learn them ....Just saying.

    he never fully explains what exactly rational numbers are. previous slide says, "all rational numbers belong to real numbers" which include decimals, but in the video, the decimals have to be changed to become fractions to be considered rational...???
