What percent of the grid is shaded? Choose the closest benchmark percent and fraction.
Solution
Step 1:
We are given a 10 × 10 grid with 100 squares. The number of shaded squares gives the percentage of shaded squares as it is out 100 squares.
Step 2:
The number of shaded squares is 11. So, the percentage of shaded squares is 11%. This is estimated to nearest benchmark percentage 10%. The equivalent benchmark fraction is therefore $frac{1}{10}$
What percent of the grid is shaded? Choose the closest benchmark percent.
Solution
Step 1:
We are given a 10 × 10 grid with 100 squares. The number of shaded squares gives the percentage of shaded squares as it is out 100 squares.
Step 2:
The number of shaded squares is 98. So, the percentage of shaded squares is 98%. This is estimated to nearest benchmark percentage 100%. The equivalent benchmark fraction is therefore 1.
What percent of the grid is shaded? Choose the closest benchmark percent.
Solution
Step 1:
We are given a 10 × 10 grid with 100 squares. The number of shaded squares gives the percentage of shaded squares as it is out 100 squares.
Step 2:
The number of shaded squares is 52. So, the percentage of shaded squares is 52%. This is estimated to nearest benchmark percentage 50%. The equivalent benchmark fraction is therefore $frac{1}{2}$
