6/9 minus 6/9 = Zero.
Two thirds minus two ninths is 4 ninths. Two thirds is 6 ninths. 6 ninths minus 2 ninths is 4 ninths.
Firstly, do 11 minus 4 = 7. So, now we have 7 and two ninths, minus five ninths. Much easier, 6 and 6 ninths.
Seven ninths minus four ninths is 1/3.
Five and one ninth.
11 - 6 5/9 = 4.4 recurring (that is, 4.4444..) or 4 and four ninths.
One whole is nine ninths. Nine ninths minus four ninths equals five ninths.
5 ninths
Anything minus itself is zero.
To subtract two fractions, they must have a common denominator. In this case, the common denominator is 9. So, convert 2/3 to 6/9. Then, subtract 6/9 - 4/9 to get 2/9 as the result.
3 6/9 or 3 2/3 or 11/3
1 third = 3 ninths, 3 ninths - 2 ninths = 1 ninth.
five-ninths, 5 _ 9
