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

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.

miv72 [106K]

No, the work is correct, but the interpretation is not. “6 is less than or equal to h<span>” means that h is greater than or equal to 6. He must grow at least 6 inches, not at most 6 inches.</span>
