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
.
Let us assume that Mark uses a model containing 100 grids.
Now, as the grids are divided into region equivalent to
i.e. it is divided into 3 parts.
Moreover, 2 out of those 3 parts will be shaded.
As, 
i.e.
=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.
I already a seed you when you asked this the first time. The answer is 3.
You multiply both sides by 50 and then you get this
(In the picture)
The answer should be (7x=21).
