En Colima se lleva acabo la conferencia sobre la energética eólica a la cual asistieron 120 representantes de Latinoamérica y Sudamérica 1/6 argentinos 1/5 chilenos 1/4 bolivianos 1/4 venezolanos y el resto de Norteamérica cuantos norteamericanos asistieron a la conferencia del energética eólica

The first thing we must do for this case is to see how many representatives from each country attended.

We have then:

Argentines = (1/6) * (120) = 20

Chileans = (1/5) * (120) = 24

Bolivians = (1/4) * (120) = 30

Venezuelans = (1/4) * (120) = 30

Adding we have:

20 + 24 + 30 + 30 = 104

Therefore the number of Americans is:

120-104 = 16

Answer:

16 Americans attended the wind energy conference
