Resposta:

Explicação passo-a-passo:

a) x/3 = 4/6 => x = 3.4/6 => x = 12/6 => x = 2

b) 3/x = 9/6 => 9x = 6.3 => 9x = 18 => x = 18/9 => x = 2

c) 5/4 = 20/x = 5x = 4.20 => 5x = 80 => x = 80/5 => x = 16

d) 8/3 = 16/x => 8x = 3.16 => 8x = 48 => x = 48/8 => x = 6

e) 2/5 = x/30 => x = 2.30/5 => x = 60/5 => x = 12
