Answer 1

Tenemos : 

40/32 = 5/x

40 (x) = 32 (5)

40x = 160

x = 160/40

x = 4

Solución : 

40/32 = 4/5
-----------------------------------------

180/450 = x/5

180 (5) = 450 (x)

900 = 450x

900/450 = x

2 = x

x = 2

Solución : 

180/450 = 2/5
--------------------------------------------------------

12/1728 = x/144

12 (144) = 1728 (x)

1728 = 1728x

1728/1728 = x

1 = x

x = 1

Solución : 

12/1728 = 1/144
----------------------------------------------------

13/x = 1/13

13 (13) = x (1)

169 = x

x = 169

Solución : 

13/169 = 1/13
