Question

In a hospital, there are 2 nurses for every 5 patients. How many nurses would probably be on duty if there were 155 patients in the hospital?

Answer 1

62

Explanation:

Easy way:
`155/2=31` Then take `2*31` to get the number of nurses which is `61`

Harder way:
`2/5*x/155` Then cross multiply. You should get `5x=310`. Then to get `x` by itself, divide both sides by `5` to get `x=62` and that's the number of nurses on duty if there were `155` patients in the hospital.
