11 with 1 remaining 100 - 1 = 99 = 9 x 11
6 of them with a remainder of 4
You can achieve a total of 100 using four 9s with the following equation: ( (99 + \frac{9}{9}) = 100 ). Here, 99 is formed by placing two 9s together, and the fraction ( \frac{9}{9} ) equals 1, which brings the total to 100.

One way: 99 + 9/9 = 100
9^2+9+9 +9/9 81+9+9+1=100
