Answer:
40% [tex](\frac{40}{100})[/tex]
Step-by-step explanation:
According to the given description of the 10 by 10 grid, 40 out of 100 squares are shaded.
Convert into a Fraction:
[tex]\frac{Shaded}{Squares} =\frac{40}{100}[/tex]
Convert the fraction into a decimal:
[tex]\frac{40}{100} =0.4[/tex]
Convert the decimal into a percent:
[tex]0.4*100=40\\[/tex]
40%
So, the grid should represent 40%.
