Answer 1

(3)原式=[ (-27) + (-9/11) ]×1/9
=(-27)×1/9 +(-9/11)×1/9
=(-3)+(-1/11)
=-34/11

(4)原式=( 3/2 +7/6 -13/12 )×(-12)
=(-12)×3/2 +(-12)×7/6 +12×13/12
=(-18)+(-14)+13
=(-32)+13
=-19

(5)原式=(-5)×(-7/9)×4/5×(-9/4)×1/7
=-(5×4/5)×(7/9×9/4×1/7)
=-4×1/4
=-1

(6)原式=1÷(7/6-35/4×2/7)+7/18×27/14
=1÷(7/6-5/2)+3/4
=1÷(-4/3)+3/4
=1×(-3/4)+3/4
=-3/4+3/4
=0

Answer 2

=(-3)+(-1/11)
