Do Now. Use the grid to answer each question. You may not know the last question, but still try to answer it. 1. How many blocks are in this grid? 2. How many blocks are shaded? 3. How many blocks are not shaded? 4. What percent of the blocks are shaded?

1. 100

2. 20

3. 80

4. 20%

Step-by-step explanation:

The Answer to number 1 is 100 as the square is 10 by 10, and the area of it can be represented by 10 multiplied by 10, or 100, and the area is equal to the number of blocks.

The Answer to number 2 is 20 as there are two columns of 10, and 2 multiplied by 10 is 20.

The Answer to number 3 is 80 as there are 100 total blocks, and 20 shaded, meaning 100-20=80 must be not shaded.

The Answer to number 4 is 20% and this is because to find the percent, we simply divide the number of shaded blocks by the number of total blocks and get 0.2. Now we just multiply that by 100 and get 20%.
