Question

Calculeaza in 2 moduri !
( 28:7)×5=
(7×3)+(5×3)=
58 +(24:6)=
(28:5)+(12:3)=
(80-56):8=
(32:4)-(18:3)=

Answer 1

( 28:7) x5 = 4x5= 20

(7x3)+(5x3)= 21+15= 36

58+ ( 24:6)= 58 + 4= 62

(28:4 ) + ( 12:3)= 7+4= 11 [ la 28:5 --> cred ca ai vrut sa scrii impartit la 4 , pt ca altfel da cu rest ;

( 80-56) : 8= 24:8= 3

( 32:4 )- ( 18:3 ) = 8-6= 2

Answer 2

1---> ( 28:7)×5= 4x5=20
2----> ( 28:7)×5= 28*5:7=140:7=20

1----> (7×3)+(5×3)=21+15=36
2-----> (7×3)+(5×3)=3(7+5)=3x12=36

1-----> 58 +(24:6)=58+4=59
2-------> 58 +(24:6)= ? *nu se poate in alt mod *

1-----> (28:4)+(12:3)= 7+4=11
2------> (28:4)+(12:3)= *nu se poate in alt mod *

1----->(80-56):8=24:8=3
2------>(80-56):8=80:8-56:8=10-7=3

1------>(32:4)-(18:3)= 8-6=2
2--------> (32:4)-(18:3)=*nu se poate in alt mod*
