each big square below represents one whole. what percent is represented by the shaded area?
each big square below represents one whole. what percent is represented by the shaded area?
Answer
Explanation:
Step1: Count total and shaded squares
Each big - square has 100 small squares. The first square is fully shaded (100 shaded squares), and the second square has 10 shaded squares. So the total number of shaded squares is $100 + 10=110$, and the total number of squares considering two whole squares is $2\times100 = 200$.
Step2: Calculate the percentage
The formula for percentage is $\text{Percentage}=\frac{\text{Number of shaded squares}}{\text{Total number of squares}}\times100%$. Substitute the values: $\frac{110}{200}\times100%$. First, $\frac{110}{200}=0.55$, then $0.55\times100% = 55%$.
Answer:
$55%$
