They are even and odd numbers respectively
If a number has an underline, it can be difficult to distinguish between a 6 and a 9. Typically, a 6 has the loop at the bottom facing downwards, while a 9 has the loop facing upwards. If the underline is drawn under the number, it may obscure the loop, but examining the shape of the number can help clarify which one it is. Context, such as the number's position in a sequence or mathematical expression, can also provide clues.
6% of 9= 6% * 9= 0.06 * 9= 0.54
do you mean what is 3+6+9-12? The answer is 6: 3+6=9 9+9=18 18-12=6 :)
6/9 = .6666 repeating.
If you mean 6 2/9, then it's (6 * 9 + 2) / 9 or 56 / 9
-3 -6 - -9 -6 = -6+9-6 = 3 - 6= -3
9
15
6% of 9= 6% * 9= 0.06 * 9= 0.54
(6 x 9) + 6 + 9 = 69
9 - (-6) = 9 + 6 = 15
6...9/9 = 118/9 = 227/9 = 336/9 = 445/9 = 554/9 = 6
15 - 9 = 6
9

3.
You need to add 6 - (-9) = 6 + 9 = 15.
