It would be easier if you converted these to improper fractions (currently it is in the form of a proper fraction)

to convert to improper fraction, you would multiply the denominator (bottom no. of fraction) by the whole number , then add that with the numerator (top no. of fraction) and put the whole thing over the denominator.

E.g.

7 = 7x4 + 1 = 29

Thus, improper fraction would be

do same thing  for other one

thus ,

now,

-

=

convert back to mixed number
