what you need to do is find the LCD (Least Common Denominator) of 9 and 12. there are a few ways to do this but you can Google those. LCD of 9 and 12 is 36 because 9 x 4 = 12 x 3
4/9 x 4 = 16/36 and 1/12 x 3 = 3/36
16/36 - 3/36 = 13/36

1/9 (one ninth)
Three twelves is 36. Four twelves is 48. 36 - 48 = -12. Three twelfths - fourth twelfths equals minus one twelfth.
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.
4/12 - 2/9 = 1/9 or one ninth.
One whole is nine ninths. Nine ninths minus four ninths equals five ninths.

1/9 (one ninth)
Three twelves is 36. Four twelves is 48. 36 - 48 = -12. Three twelfths - fourth twelfths equals minus one twelfth.
One fourth is three twelfths. So eleven twelfths minus three twelfths is eight twelfths, which is also two thirds.
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.
Three-twelfths is equal to one quarter. Three-ninths is equal to one third. One third of anything is a greater quantity than one quarter of anything, therefore, "Three-ninths" is the larger of the two.
seven twelfths
six twelfths
Eight minus one and one ninth equals six and eight ninths.
