Question:

+-9%2F2+%2B+3%2F4+

Here the denominators are different....
So at first convert make the denominators same...


Here Least Common Divisor(LCM) of 2 and 4 is 4

==> +%28-9%2F2%29+%2A+%284%2F4%29

==> +%28-9%2F1%29+%2A+%282%2F4%29


==> +%28-9%2A2%29%2F4


==> -18%2F4

Now, +%283%2F4+%29%2A+%284%2F4%29


==> 3%2F4


that is ....

+-9%2F2+%2B+3%2F4+ = %28-18%2F4%29+%2B+%283%2F4%29



==> +%28-18%2B3%29%2F4



==> +-15%2F4




Hope you found the explanation useful.
