write a ratio and percent for the shaded area.
total of 20 squares 6 shaded squares
A. 6/25 30%
B. 3/50 6%
C.6/25 24%
D.3/10 30%
so shaded part = 6/20 = 3/10 or 30%
To find the ratio and percent for the shaded area, we need to determine the fraction of shaded squares out of the total squares and then convert it into a percentage.
There are 6 shaded squares out of a total of 20 squares.
Step 1: Ratio
The ratio is found by dividing the number of shaded squares by the total number of squares.
Therefore, the ratio of shaded squares to the total squares is 6/20.
Simplifying this ratio gives us 3/10.
Step 2: Percentage
To convert the ratio into a percentage, multiply it by 100.
Percentage = (Ratio) x 100%
= (3/10) x 100%
= 30%
Therefore, the correct answer is option D: 3/10 30%.
