1.(a×b+a×c)÷8=(45+35)÷8=80÷8=10
2.(a×b-a×c)÷2=(45-30)÷2=10÷2=5
1.(a×b+a×c)÷6=(36+12)÷6=48÷6=8
2.(a×b-a×c)÷4=(36-12)÷4=24÷4=6
sper ca te-am ajutat....
1) a×(b+c):8=
=(a×b+a×c):8=
=(45+35):8=
=80:8=10
2) a×(b-c):2=
=(a×b-a×c):2=
=(45-35):2=
=10:2=5
1) a×(b+c):6=
=(a×b+a×c):6=
=(36+12):6=
=48:6=8
2) a×(b-c):4=
=(a×b-a×c):4=
=(36-12):4=
=24:4=6
