Answer:

1600 people

Explanation:

This is a ratio problem. We can set up the proportion by letting x be the number of people who applied for admission:

(4)/(10)=(640)/(x)

Since we know that 4 people get in for every 10 people that apply, we can set up an equation like the one above and solve for x by cross multiplying:

$6400=4x\\x=1600$

This means that 1600 people applied for admission to the vocational school.
