Question

me pueden ayudar por favor no entiendo ​

Answer 1

Explicación paso a paso:

Resolviendo se tiene:

S = ([(5-1)/5][(3-1)/3][(4-1)/4])/[(3/2)(3/5)]

S = ([4/5][2/3][3/4])/(9/10)

S = (24/60)/(9/10)

S = (24*10)/(60*9)

S = 240/540

Supresión:

S = 120/270 = 60/135

S = 60/135 = 20/45

S = 20/45 = 4/9

"S" vale 4/9.
