#13/4# OR #3 1/4#

Explanation:

  • first you work out what is in the brackets
    that is #1/3÷1/6# to give you 2 as you answer
  • second step rewrite the whole question replacing two in the place of #1/3÷1/6#
  • so you will have #3/4+2 - (-1/2)#
  • thirdly open the brackets with the negative sign outside the bracket that is: # - (-1/2)# so that you get #+1/2# (or #1/2#, basically)
  • lastly rewrite the whole question
  • so you will have #3/4+2 +1/2#, you add all of them ... #3/4+8/4+2/4=13/4#

extra:

you can keep that solution, or you can change it from improper fraction to a mixed number

if you use long division, #13\div4=3# with a remainder of #1# over #4#.
doing this by calculator you get 3.25, which is basically #3 25/100=3 1/4#
