Question

hallar el valor de x en cada simplificasion
40 5
_____:x
32

Answer 1

Respuesta:

40/32 = 5/x

40x = 5*32

40x = 160

x = 160/40

x = 40

180/450 = x/5  simplificamos  180/450 = 18/45

18/45 = x/5 

18*5 /45 = x

90/45 = x

2 = x

x = 2

12/1728 = x/144

12*144/1728 = x

1728/1278 = x

1 = x

x = 1

13/x = 1/13

13 = x/13

13*13 = x

169 = x

x = 169
