a ratio is a comparison of two things by division. there are three main ways to express ratios -
as percents, as fractions, and as decimals. in the percents, fractions, and decimals gizmo,
you can model percents, fractions, and decimals for values from 0 to 1.
the grid can be adjusted to contain from 1 to 300 squares by dragging the
handle at the bottom-right corner. each square can be shaded or unshaded
by clicking in it. you can also click and drag to shade multiple squares.
1. create a grid that is 5 squares wide by 2 squares tall. shade 8 squares, as shown above.
a. look at the shaded: total row in the gizmo table. what decimal and percent are
modeled by the shaded squares? decimal =
percent =
b. look at the unshaded: total row. what decimal and percent are modeled by the
unshaded squares?
decimal =
percent =
