(99)/(99) +9.

11 with 1 remaining 100 - 1 = 99 = 9 x 11

99 plus 9/9 = 100

1/99 = 0.01 01 01 .. .. 99 is a Kaprekar number (as is any string of 9s) : 992 = 9801 and 98 + 01 = 99

(99/9) + sqrt(9) = 14

Five 9s:(99 x 9 + 9) / 9 = 100

It is 99.

11 with 1 remaining 100 - 1 = 99 = 9 x 11

One way: 99/9 - 9/9

99 plus 9/9 = 100

9÷9+99 or 99+9÷(9)

1/99 = 0.01 01 01 .. .. 99 is a Kaprekar number (as is any string of 9s) : 992 = 9801 and 98 + 01 = 99

(99/9) + sqrt(9) = 14

9 + (9/9) = 10(99/9) - (9/9) = 10

Take two 9s and make them a fraction like this 9/9. Then put the other two 9s together to make 99 and you get 9/9+99=100. Because 9/9=1 so it becomes 1+99=100.

There are exactly 20 Nines. 9,19,29,39,49,59,69,79,89,90,91,92,93,94,95,96,97,98 which totals 18 and the last number 99 has 2 nines and therefore 20 nines in total.
