999 + 9/9 = 1000
(99/99) + 9 = 10 alternative method: 99/9 - 9/9
99 + 9(9-9)
9 / 9 + 9 = 10.
9x9+9+9+9/9
9 + 9 + (9/9) = 19
99+sqt9xsqt9/9
9 + 9 + 9/9 + (9 x 9) = 100
( 9+9+9) / (9+9+9)= 1 or 999 /999 = 1
99/9=11
208 times,from 1 to 100 there r 11 nine such as 9 , 19 , 29, 39, 49,59, 69,79, 89, 99 its prove there are 11 nines so up to 800 there are 11*8=88 nines and from 900 to 1000 there are 100(901, 902,903......)+ 10 ( 990,991,992.....)+10(909,919,929,939....)=120 that means there are in total 88+120=208 nine in 1 to 1000
9000. 9000/9=1000 9000/10=900
