Answer 2

40%
`((40)/(100))`

Explanation:

According to the given description of the 10 by 10 grid, 40 out of 100 squares are shaded.

Convert into a Fraction:

`(Shaded)/(Squares) =(40)/(100)`

Convert the fraction into a decimal:

`(40)/(100) =0.4`

Convert the decimal into a percent:

`0.4*100=40\\`

40%

So, the grid should represent 40%.
