Answer:
66 + 1 ( not fully shaded ) squares will be shaded.
66.67% region will be shaded
Step-by-step explanation:
It is given that Marks uses a grid to model percent equivalent of [tex]\frac{2}{3}[/tex].
Let us assume that Mark uses a model containing 100 grids.
Now, as the grids are divided into region equivalent to [tex]\frac{2}{3}[/tex] i.e. it is divided into 3 parts.
Moreover, 2 out of those 3 parts will be shaded.
As, [tex]\frac{2}{3} =0.6667[/tex]
i.e. [tex]\frac{2}{3}[/tex]=66.67%
So, it gives us that 66 squares in the grid will be fully shaded and one will not be fully shaded.
Hence, 66 + 1 ( not fully shaded ) squares will be shaded and in percent, 66.67% of the region will be shaded.
