Question

Of 130 patients in a hospital, 70% of them are checked in for the flu. How many patients are not checked in for the flu?

Answer 1

First let's find the number of patients checked in:
$x = (130)0.70 \\ x = 91$
we know that 91 patients were checked in, so we can find how many were not:
$z = 130 - 91 \\ z = 39$
39 patients were not checked in for the flu.

Answer 2

39!      

Explanation:

70% of 130 is 91  

70 x 130/

100

= 91 you do 70 time 130 divided by 100 which gets you to 91 so that means 91 patience have the flu to find how many don't have the flu you subtract 130-91 that gives you 39!
