mi ajuuuuuude! Calcule as proporções! pra amanhã !

Answer 1

1- a\ 
3x= 36
x= 36/3 
x = 12

1b\ 3x= 60
x=60/3
x=20

1c\ 8x=   90
x= 90/8= 11,25

1d\  3x= 32
x= 32/3
x= 10,6

1e\ 3x=  3
x= 3/3 
x= 1

1f\ 0,4x= 2
x= 2/0,4
x= 5

2a\ 12x=60
x= 5

2b\ 14x= 42
x=3

2c\ 9x= 63
x=7

2d\ 10x= 10
x=1

2e\ 10x= 60
x=6

2f\ 40x= 120
x=3
