25 numbers are between 1-100.
It is 90
A repeating decimal is a rational number. Its value is(the repeating set of digits)/(as many 9s as there are digits above).
100
11 with 1 remaining 100 - 1 = 99 = 9 x 11
Five 9s:(99 x 9 + 9) / 9 = 100
111 of them with a remainder of 1
9^2+9+9 +9/9 81+9+9+1=100
There are: 640/9 = 71 with a remainder of 1
99 plus 9/9 = 100
8, remainder 1
1 or 4 , depending on your point of view.
(9*9)+(9+9)+(9/9) = 100
5
Nine of them
