Question

Calcule o valor de x nas proporções
g)14/6=x/9
h)15/60=60/x
i)2x/15 =6/9

Answer 1

→ Cálculo :

G) 14/6 = x/9

6 · x = 9 · 14

6x = 126

x = 126 ÷ 6

x = 21

H)15/60 = 60/x

15 · x = 60 · 60

15x = 3600

x = 3600 ÷ 15

x = 240

I) 2x/15 = 6/9

2x/15 = 2/3

2x · 3 = 15 · 2

6x = 30

x = 30 ÷ 6

x = 5
