Question

The ratio of enlisted men to officers in a division is 25 to 1.

If there are 1000 enlisted men, how many officers are in the
division?

Answer 1

The answer is 40.

1000/25 will give you the new ratio

Simple way of thinking about it

25 enlisted men = 1 officer
1000enlisted men = X officer

Cross multiply (25 by X officer and the 1 officer by the 1000)

25x = 1000

X= 40.
