Question

5. The model below shows the ratio of gray squares to white squares. Which of the following is NOT an equivalent ratio of gray squares to white squares?

Answer 1

there are 5 white blocks and 4 gray blocks.

so the ratio of the gray square to white square is,

`\frac{\text{gray}}{\text{white}}=(4)/(5)`

multiply numerator and denominator by 5.

`\frac{\text{gray}}{\text{white}}=(4)/(5)*(5)/(5)=(20)/(25)`

so the answer is option D
