Answer 1

c) (3/8-5/6)+(-1×1/4)=
    9-20/ tot supra 24 +(-1/4)=
    (-11/24)-1/4=
    -11/24-1/4=
    -11+6/ tot supra 24=
    -17/24.
d) 3×5/14-(11×1/4-6×1/6)=
    15/14-(11/4-1)=
     15/14-/11-4/ supra 4=
     15/14-7/4=
     30-49/ tot supra 28=
     -19/28.
e) -4.7-(-2.6+6.2)=
    -4.7-3.6=-8.3.
f) 2.(3)-(-1.5)-1/4=
