See a solution process below:

We need to put each fraction over a common denominator by multiplying the fraction on the right by the appropriate form of #1#:

#12/35 + (5/5 xx 4/7) =>#

#12/35 + (5 xx 4)/(5 xx 7) =>#

#12/35 + 20/35#

We can now add the numerators over the common denominator:

#(12 + 20)/35 =>#

#32/35#
