4/12 - 2/9 = 1/9 or one ninth.
two ninths
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.
Two quarters minus two thirds is negative one sixth. Two quarters is six twelfths, and two thirds is eight twelfths. Six twelfths minus eight twelfths is minus two twelfths or minus one sixth.
Expressed as a proper fraction in its simplest form, 4/9 - 2/3 = -2/9 or minus two ninths.
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.
six ninths is equivalent to eight twelfths.
3 6/9 or 3 2/3 or 11/3
One fourth is three twelfths. So eleven twelfths minus three twelfths is eight twelfths, which is also two thirds.
Converting to twelfths gives 9 twelfths minus 8 twelfths which is 1 twelfth.
-8 and 2/9
23 and seven ninths.
