1.) 6/7 - 4(3/5 +6)= 6/7 - 4(3+30)/5 = 30/35 - 28(33)/35 =
(30 - 924)/35 = -894/35 = -25.5
2.) I don't know
3.) (9x5) + (7x5) + 4 = 45 + 35 + 4 = 84
4.) 7 - (6 x 12) = 7 - 72 = 65
5.) 2
6.) 8 - ( 60) = 52

I think there are some operands missing from #3 and #5 so I can't help you.

edit. I missed the very first one.
it comes out to -894/35. You can simplify that.

1) 6/7-4(3/5+6)=6/7-4[(3+30)/6]=6/7-4[33/6]=6/7-22=[6-154]/7= -148/7= -22 1/7
2)D
3)[5(9+7)]+4=[5(16)]+4=80+4=84
4)-(-7) -6(43)=7-258= -251
5)2
6)-(-8)-9(106)=8-954= -946

I am not good with any kind of math so I can't help you out. I suggest you ask your teacher for help.
