2 and 1/12
It is: 12-5/8 = 11 and 3/8 or 11.375
-1 5/8
1 whole = 4 fourths 4 wholes = 16 fourths 4 wholes minus 2 fourths = 16 fourths minus 2 fourths = (16 - 2) fourths = 14 fourths 14 fourths = 3 wholes plus 2 fourths, or 3 wholes plus 1 tooth.
8.66-3.86=4.8=4 wholes and 17 over 21
It is 5 3/7.
1 1/3
4 − 23/8 = 13/8 or 15/8
3
3 - (-12) = 3 + 12 = 15.
I believe that there are 32 fourths in eight wholes.
31/3 − 2/3 = 8/3 or 22/3
