Question

Hallar El Valor De x En Cada Simplificacion
40/32=5/x

180/450=x/5

12/1.728=x/144

13/x=1/13

Answer 1

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
