5 and 4/9
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.
11 - 6 5/9 = 4.4 recurring (that is, 4.4444..) or 4 and four ninths.
5 ninths
Firstly, do 11 minus 4 = 7. So, now we have 7 and two ninths, minus five ninths. Much easier, 6 and 6 ninths.
6 - 5/9 = 5 4/9
five-ninths, 5 _ 9
It is: 5/9
two ninths
5/9 minus 5/12 is 5/36.
two and two thirds
5 ninths. (5/9)
