12(7/12)-

then simplify
seven twelfths
seven twelfths
4/12 - 2/9 = 1/9 or one ninth.
7/12 minus 1/3 is 1/4.
seven ninths
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.
one ninth
127/12 - 51/9 = 151/12 - 46/9 = 453/36 - 184/36 = 269/36 = 717/36
six twelfths
five twelfths 1/6 = 2/12 7/12 - 2/12 = 5/12
one minus eleven twelfths = 1 - 11/12 = 12/12 - 11/12 = 1/12
