11 5/9 - 4 2/3 =7 8/9
Firstly, do 11 minus 4 = 7. So, now we have 7 and two ninths, minus five ninths. Much easier, 6 and 6 ninths.
5/9 minus 2/3 equals -1/9
-8 and 2/9
Five and four-ninths
There is one third in five ninths, with a remainder of two ninths. Six ninths would be equal to two thirds.
One whole is nine ninths. Nine ninths minus four ninths equals five ninths.
five-ninths, 5 _ 9
five ninths
2/9
1 third = 3 ninths, 3 ninths - 2 ninths = 1 ninth.
One and two ninths
Nine and five-ninths minus six and five-sixths = 49/18 or 213/18
