a). 0.45 with a line over the 45 means 0.45454545454545... forever.
It's equivalent to 45/99 which is 5/11 .
b). 0.45 with a line over the 5 means 0.455555555... forever.
It's equivalent to (0.4 + 0.555555.../10)
The 0.4 part is 4/10
The 0.5555555555.../10 part is 5/90 .
(4/10) + (5/90) = 41/90
c). 0.45 means 45/100 . That's 9/20 .
