Question

Calcule o valor de x das proporções a seguir: a)1,5/3 =x/2 b)3/x = 5/10 c-) x/2 =4/2 d) 1/3 = 12/x

Answer 1

a)1,5/3 =x/2

3x = 1,5×2

3x = 3

x = 3/3

x = 1

b)3/x = 5/10

5x = 3×10

5x = 30

x = 30/5

x = 6

c-) x/2 =4/2

2x = 2×4

2x = 8

x = 8/2

x = 4

d) 1/3 = 12/x

x = 3×12

x = 36
