Count the total number of squares.
There are 10 by 10 of them or:
[tex]\sf 10\cdot 10=100[/tex]
So there are a total of 100 squares, now count the shaded squares.
[tex]\sf 4\cdot 4=16[/tex]
There are 16 shaded squares out of 100, this is a fraction:
[tex]\sf\dfrac{16}{100}=\boxed{\sf 0.16}[/tex]
So your answer is C.
