Question

Calcule a terceira proporcional em cada item

A) 5 = 3 C) 7 = 10 E) 26 = 26
5 X 7 X 10 X

B) 4 = 9 D) 13 = 13 F) 36 = 10
X 4 X 30 10 X

G) 4/2 = 6/3 H) ½ = 3/2
X 6/3 ½ X

ME AJUDEM POR FAVOR, SO PEÇO ISSO​

Answer 1

Resposta:

Basta multiplicar cruzado (em forma de cruz)

a) 5x = 3.5

5x = 15

x = 15/3

x = 3

b) 4.4 = 9x

x = 16/9

c) 7x = 7.10

7x = 70

x = 70/7

x = 10

d) 13x = 30.13

x = 30.13/13

x = 30

e) 26x = 26.10

x = 26.10/26

x = 10

f) 36x = 10.10

x = 100/36

g) 4/2.6/3 = 6/3x

x = 4/2.6/3/6/3

x = 4/2

h) 1/2x = 3/2.1/2

x = 3/2.1/2/1/2

x = 3/2
