To convert the decimal number 0.99 to a fraction using the given formula, we can assign DN as 0.99, F as 100, and D as 99.
Substituting these values into the formula:
((0.99 x 100) - 0.99) / 99
Simplifying:
(99 - 0.99) / 99
98.01 / 99
So, the fraction form of the decimal 0.99 is 98.01/99.

To convert the decimal number 0.91 to a fraction using the given formula, we can assign DN as 0.91, F as 10, and D as 9.
Substituting these values into the formula:
((0.91 x 10) - 0.91) / 9
Simplifying:
(9.1 - 0.91) / 9
8.19 / 9
To express this fraction in simplest form, we can divide both the numerator and the denominator by their greatest common divisor, which is 1 in this case.
8.19 / 9 is already simplified.
Therefore, the fraction form of the decimal 0.91 is 8.19/9.
