In changing percent to decimal, you'll have to note that
you move two(2) decimal places to the left of the percent value and you'll put the decimal point in there.
Examples:
100% = move 2 decimal places to the left
100% = 1 (in decimal)
98% = move 2 decimal places to the left
98% = 0.98 (in decimal)
12% = move 2 decimal places to the left
12% = 0.12 (in decimal)
5% = move 2 decimal places to the left
5% = 0.05
