I remember watching one of Jasons older videos and he said something I never forgot that always helps me with fractions, it is that there is an implied 1 over every number and then it helps me figure out how to solve the problem. In this video take 1.5, well there is an implied 1.5/1 so multiply numerator and denominator by 2 and you get the 3/2 in this example. Ill always be thankful that he taught me that.
