(99)/(99) +9.
Five 9s:(99 x 9 + 9) / 9 = 100
9 + (9/9) = 10
It is five.
9 + (9/9) = 10(99/9) - (9/9) = 10
Ninety nine divided by nine equals eleven
Yes, there are an infinite number of posibilities. Staying only with positive odd numbers, if duplicates are allowed, then five 9s and five 11s make 100. If duplicates are disallowed, then 1 + 3 + 5 + 7 + 9 + 11 + 13 + 15 + 17 + 19 = 100
10 times
wait not the discription srry
1*10**-9s
One way: 99/9 - 9/9
The GCF of 9s and 63s^3 is 9s.
