Firstly, do 11 minus 4 = 7. So, now we have 7 and two ninths, minus five ninths. Much easier, 6 and 6 ninths.
11/6 minus 2/9 is 1 11/18
6 - 5/9 = 5 4/9
It is: 8/9 minus 5/6 = 1/18
-5 - 6 = -11
Firstly, do 11 minus 4 = 7. So, now we have 7 and two ninths, minus five ninths. Much easier, 6 and 6 ninths.
Two thirds minus two ninths is 4 ninths. Two thirds is 6 ninths. 6 ninths minus 2 ninths is 4 ninths.
6/9 minus 6/9 = Zero.
3 6/9 or 3 2/3 or 11/3
11 minus 5 is 6
11/6 minus 2/9 is 1 11/18
6 - 5/9 = 5 4/9
6/11 minus 5/6 equals -19/66
-5 - 6 = -11
12 minus 11 1/6 is 5/6
11 - 5 = 6
It is: 8/9 minus 5/6 = 1/18
