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.
1m = 100 cm 1 meter = 100 centimeters
It is 90
25 numbers are between 1-100.
100 "cent" means 100 as in 100 cents = $1
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
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.
1 ns (nanosecond) = 10-9s 1s / 10-9s = 109 109 = 1000 000 000 1 second = 1000 000 000 ns (nanosecond)
