Question

Write a ratio and a percent for the shaded area. A 3/10, 27% B. 1/2, 50% c. 1/3, 33.33% D. 3/10,30%

Answer 1

Ratios and percents

The total number of squares is 6x6 = 36

the number of squares of the shaded area is 3x4 = 12

Ratio

We find the ratio by dividing those two quantities:

`(12)/(36)=(1)/(3)`

Percentage

We find the percentage by multiplying the result by 100%

`(1)/(3)*100=0.333*100=33.33`

Answer: C. 1/3 = 33.33%
