Question

Determine o valor de x, para que se tornem equivalentes: a)2/3=x/6 b)6/4=x2 c)x/5=9/4 d)27/36=x4

Answer 1

Oi....

Multiplique cruzado.

a)

2/3 = x/6

3.x = 2.6

3x = 12

x = 12/3

x = 4

2/3 = 4/6

b)

6/4 = x/2

4.x = 6.2

4x = 12

x = 12/4

x = 3

6/4 = 3/2

c)

x/5 = 9/4

4.x = 5.9

4x = 45

x = 45/4

x = 11,25

11,25/5 = 9/4

d)

27/36 = x/4

36x = 27.4

36x =108

x = 108/36

x = 3

27/36 = 3/4
