Question

What decimal of a whole is represented by the entire grid?

• A. 1.66
• B. 0.66
• C. 66
• D. 6.6

Answer 1

The correct option is B 0.66

There are a total of 10 strips of 10 blocks each in this grid.
Here,
6 strips are shaded completly and in the seventh strip 6 blocks are painted.
So, in total 66 blocks are painted.
So, the fraction of the grid that is shaded = $\frac{66}{100}$

Thus, the decimal representation of the grid that is shaded = 0.66
