Question

what percentage of the shape is blue? write your answer using a percent sign (%).

Explanation:

Step1: Count total and blue parts

The circle is divided into 10 equal parts (assuming, as the diagram shows 10 sectors? Wait, no, looking at the diagram, let's count again. Wait, the circle has 10? Wait, no, maybe 10? Wait, no, let's see: the circle is divided into 10 equal - sized sectors? Wait, no, actually, looking at the diagram, the circle is divided into 10 parts? Wait, no, maybe 10? Wait, no, let's count the number of blue sectors. Wait, the entire circle is blue? Wait, no, wait the diagram: the circle is divided into 10 equal sectors? Wait, no, maybe I miscounted. Wait, the circle is a whole, and if it's divided into 10 parts? Wait, no, actually, the circle is fully blue? Wait, no, wait the problem: the shape is a circle, and all the sectors are blue? Wait, no, let's check again. Wait, the circle is divided into 10 equal - sized sectors, and all of them are blue? Wait, no, maybe the circle is divided into 10 parts, and all are blue. So total parts \( n = 10 \), blue parts \( b=10 \).

Step2: Calculate percentage

The formula for percentage is \( \text{Percentage}=\frac{\text{Number of blue parts}}{\text{Total number of parts}}\times100\% \). Substituting the values, we get \( \frac{10}{10}\times 100\%=100\% \). Wait, maybe I made a mistake. Wait, no, looking at the diagram again, maybe the circle is divided into 10 parts, and all are blue. So the percentage of blue is 100%.

Answer:

100%
