Given: A figure showing shaded squares and unshaded squares
To Determine: The ration of the shaded squares to the unshaded squares
Solution
Count the number of shaded squares and the number of unshaded squares
From the above,
[tex]\begin{gathered} N_{shaded}=10 \\ N_{unshaded}=15 \end{gathered}[/tex]
Therefore, the ratio of the shaded to unshaded squares would be
[tex]\frac{N_{shaded}}{N_{unshaded}}=\frac{10}{15}=\frac{2}{3}[/tex]
Hence, the ratio of the shaded to unshaded squares is 2/3, OPTION B
