Represent a fraction1/b on a number line diagram by defining the interval from 1 as the whole and partitioning it into b equal parts. Recognize that each part has 1/b and that the endpoint of the part based at 0 locates the number 1/b on the number line. Represent a fraction a/b on a number line diagram by marking off a lengths 1/b from 0. Recognize that the resulting interval has a size a/b and that its endpoint locates the number a/b on the number line.
