Question

What is the ratio of shaded to unshaded squares in the grid below

Answer 1

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,

`\begin{gathered} N_(shaded)=10 \\ N_(unshaded)=15 \end{gathered}`

Therefore, the ratio of the shaded to unshaded squares would be

`(N_(shaded))/(N_(unshaded))=(10)/(15)=(2)/(3)`

Hence, the ratio of the shaded to unshaded squares is 2/3, OPTION B
