3-131.

The following representations have been drawn to represent portions of a 100% block. Write each of the portions in at least two different forms.

  1. A 100% block with 5 squares in the first column shaded.

  • How many blocks are filled in? How could you represent this in writing?

    Since 5 blocks out of 100 are filled in, it can be expressed in two ways.

  1. A 100% block with 7 columns, and 5 squares in the sixth column, shaded.

    Use part (a) as a guide, because this problem is very similar.

    How many blocks are filled in? What portion of the whole does this represent?
