9/10 divided by 10/9 equals 9/10 x 9/10 equals 81 /100
9 + (9/9) = 10(99/9) - (9/9) = 10
9/9 ÷ 10 = 1/10
9 + (9/9) = 10 (99/9) - (9/9) = 10 [ (9 + 9 + 9 + 9 + 9 + 9 + 9 + 9 + 9) / 9 ] + (9/9) = 10
9 + 9 + 10 + 10 = 38
9*11 = 9*(10 + 1) = 9*10 + 9*1 = 9*10 + 9.
Its positional place value is 9/10 = nine tenths
3.90*10-9 nanometres is exactly 3.90*10-9 nanometres.3.90*10-9 nanometres is exactly 3.90*10-9 nanometres.3.90*10-9 nanometres is exactly 3.90*10-9 nanometres.3.90*10-9 nanometres is exactly 3.90*10-9 nanometres.
I'm not quite sure if this is what you mean but: 9/9=1 9+1=10 9/9=1 10*1=10 The whole thing: (9/9)*(9+(9/9))=10
Nineteen = 9 plus 10 = 9 + 10
(7/9) / (9/10) = (7/9) * (9/10) = 7/10 = 0.7
