Question

Calculați în două moduri:
A)
(35+5):5=
(35-25):5=
(36+24):6=
B)
(18+30):6=
(28+35):7=
(49-21):7=​

Answer 1

Explicație pas cu pas:

A

1)(35+5):5=40:5=8

2) (35:5)+(5:5)=7+1=8

1) (35-25):5=10:5=2

2) (35:5)-(25:5)=7-5=2

1) (36+24):6=60:6=10

2) (36:6)+(24:6)=6+4=10

B

1) (18+30):6=48:6=8

2) (18:6)+(30:6)=3+5=8

1) (28+35):7=63:7=9

2) (28:7)+(35:7)=4+5=9

1) (49-21):7=28:7=4

2) (49:7)-(21:7)=7-3=4
