First you have to find the least common denominator:
2. 32 3/4 -12 1/2 lets work fractions first;
=3/4 -1/2 LCD (least common denominator) is 4 because both numbers                        can go into this number.
=3/4 - 2/4 To get this both bottom numbers has to be LCD and to do this                       since two goes into 4 twice you times the numerator by two
=1/4          Subtract
32-12=20  Now lets subtract the whole numbers
So the answer to number 2 is 20 1/4

3. 517 37/50 + 312 3/100 =
    517 74/100 + 312 3/100 =
     829 77/100 =
4. 632 16/25 + 32 3/10 =
    632  32/50 + 32 15/50 =
     664 47/50 =
5. 421 3/50 - 212 9/10 =
    421 3/50 - 212 45/50=
     633 48/50 ≈ 633 24/25=
Please check all my work to ensure it is right I did not use a calculator. If you need more help let me know :)
