Verified answer

Explicación paso a paso:

1)  

5/9 = x/45

5(45)=x(9)

225=9x

225/9=x

25=x

4.5/x=13.5/16.5

(4.5)(16.5)=(13.5)x

74.25=13.5x

74.25/13.5=x

5.5=x

2)

7/2=42/x

(7)x=42(2)

7x=84

x=12

48/x=6/4

(48)(4)=6x

192=6x

32=x

Answer 2

Respuesta:

1)R//

a) 5/9 = x/45

45(5) = 9x

225 = 9x

225/9 = 9x/9

25 = x

x = 25

b) 4,5/x = 13,5/16,5

(4,5)(16,5) = 13,5x

74,25 = 13,5x

74,25/13,5 = 13,5x/13,5

5 , 5 = x

x = 5 , 5

2)R//

a) 7/2 = 42/x

7x = 42(2)

7x = 84

7x/7 = 84/7

x = 12

b) 48/x = 6/4

4(48) = 6x

192 = 6x

192/6 = 6x/6

32 = x

x = 32
