Question

Mark wants to use a grid to model the percent equivalent of the fraction 2/3. How many grid squares should be shade? What percent would his model show?

Answer 1

He should use a 3x3 grid, so 9 squares in total. Mark should then shade in 6 of those 9 boxes. 6/9 = 2/3. He would have shaded in 66.666666% roughly.

Answer 2

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 $\frac{2}{3}$.

Let us assume that Mark uses a model containing 100 grids.

Now, as the grids are divided into region equivalent to $\frac{2}{3}$ i.e. it is divided into 3 parts.

Moreover, 2 out of those 3 parts will be shaded.

As, $\frac{2}{3} =0.6667$

i.e. $\frac{2}{3}$=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.
