Answer 2

Answer:

7/13

Step-by-step explanation:

x+y=5/2+(-3/4)

=5/2-3/4 (as plus into minus is equal to minus)

=(10-3)/4 ( as LCM of 2 and 4 is 4)

=7/4

x-y=5/2-(-3/4)

=5/2+3/4 ( as minus into minus is equal to plus)

=(10+3) /4 ( as LCM of 2 and 4)

=13/4

therefore,(x+y) ÷(x-y)

=7/4 ÷13/4

=7/4*4/13

=7/13
