0.bar(91)
91/1000
91/99
41/45
-65/90
To write the decimal 0.bar(91) as a fraction, we can use the formula:
(DN x F) - NRP
D
In this case, DN = 91, F = 100, and D = 99.
Substituting these values into the formula, we get:
(91 x 100) - 91
-----------------
99
Simplifying this expression, we have:
9100 - 91
-----------
99
9019
-----
99
Therefore, the correct answer is:
91/99
