#1/4-(-3/8)=1/4+3/8=5/8#

Explanation:

Subtracting a negative fraction #B# from a positive fraction #A# means adding the number part of it (that means leaving the minus sign) to #A#.

For example if we have to subtract #-3/8# from #1/4# means, adding #3/8# to #1/4# or #1/4+3/8# and as #1/4# equal to #2/8#, #1/4+3/8=2/8+3/8=(2+3)/8=5/8#

Hence #1/4-(-3/8)=1/4+3/8=5/8#.
