3-75.

Find the missing parts of each number line. Assume that the lines have been split into equal parts.  

  1. Line segment divided into 6 equal sections, first mark labeled 0, and last mark labeled 42. A bracket includes the first 2 sections and is labeled with a question mark.

    Find the length of each segment. Then multiply that number by the number of segments in the missing part.

    The segments are units long, and there are two segments in the missing part.

  1. Line segment divided into 8 equal sections, first mark labeled 0, and last mark labeled 64. A bracket includes the second through sixth sections, and is labeled with a question mark.

    Use the method from part (a).
