You can determine the answer by inspection!!

Note that

#6 1/2 - 4 1/2 = 2#
(the fractions are the same, so they give 0, work with the whole numbers .

#5 2/3 - 2 2/3 = 3#

In the example #2 7/10 - 3 7/10# the only difference is that we will end up with #-1#

Look at the maths:

#2 7/10 - 3 7/10 = 2 -3 + 7/10 - 7/10#

=#-1 +0#

=#-1#
