What number is represented by each of the letters on the number lines below?

  1. Number line, with 8 equal mark, labeled as follows, starting from the left: first,  is  A, second is 0, fourth is B, sixth is 12, and seventh is C.

    Count the number of marks from one given number to the next.

    There are four marks from to . How much does each mark represent?

    If four sections represent a total of , then each unit must represent .

    Use the knowledge that the marks are made every integers to determine what A, B, and C represent.

  1. Vertical number line, with 7 equal marks, labeled as follows, starting from the bottom: first is D, second is 0, fourth is 700, fifth is E, and seventh is F.

    D represents . Why does that make sense? Now use that to figure out the values of the other points.
