• B. 76%, 0.76
• C. 24%, 0.76
• D. 24%, 0.24

Answer 1

The correct option is C 24%, 0.76

The grid given is a 10x10 grid.It contains 100 squares.
Out of this, 24 squares are shaded in blue.
Hence the percentage of the shaded portion is 24 parts out of 100, which is 24%
The number of non shaded squares = 100 - 24 = 76
$\Rightarrow$ 76 squares are not shaded, that is 76% is not shaded.
76% expressed asa decimal is $\frac{76}{100}$ = 0.76
