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=
2.(3)+1.5-0.25=
3.55..........sper ca team ajutat........../liniea inseamna supra/
