Question

qual o valor de x nas proporcoes ?
a-x/3=8/12=
b-2/x=14/21=
c-1/6=5/x=
d-12/x=3/2=
e-3/x=9/3=
f-2/8=6/x=
g-15/30=x/2=

Answer 1

A-  $\frac{x}{3}$ = $\frac{8}{12}$
     X = $\frac{8}{12}$ × 3
     X = 2.

B-  $\frac{2}{x} = \frac{14}{21}$
     2 = 14/21 × X
     3 = X

C- 1/6 = 5/X
    1/6 × X = 5
    X = 30.

D- 12/X = 3/2
     12 = X × 3/2
     X = 8

E- 3/X = 9/3
    3 = 9/3 × X
    X = 1

F- 2/8 = 6/X
   2/8 × X = 6
   X = 24

G- 15/30 = X/2
     X = 15/30 × 2
     X = 1

Espero ter ajudado ☺

Abraços!
