Answer 1

Răspuns:

Explicație pas cu pas:

60 : 2 = 90 : 3

60 : 2 x 3 = 30 x 3 = 90

___________________

80 : 4 = 40 : 2

80 : 4 x 2 = 20 x 2 = 40

___________________

600 : 3 = 800 : 4

600 : ( 800 : 4 ) = 600 : 200 = 3

________________________

400 : 2 = 600 : 3

400 : ( 600 : 3 ) = 400 : 200 = 2

__________________________

900 : 3 = 30 x 10

30 x 10 x 3 = 300 x 3 = 900

________________________

40 : 4 = 100 : 10

( 100 : 10 ) x 4 = 10 x 4 = 40
