There are 100 squares in the grid.
63 are shaded.
Number of squares shaded is the numerator (number on top of the decimal).
Total number of squares is the denominator (number at the bottom of the decimal).
Whenever the denominator of the fraction is 100, you can just take the numerator and put a decimal behind the number.
Therefore, the decimal represented would be 0.63.
