Answer:

Hi!

The answer is: 1.804.000 cockroaches are immune.

Step-by-step explanation:

To solve this problem, you can use <em>the rule of three</em>.

     100 ----> 2.200.000 cockroaches  // If 100% is 2.200.000 cockroaches

     82 ----> x cockroaches  // then 82% will be immunes.

Now, multiply 82 by 2.200.000 and divide the result by 100:

x =\frac{82*2.200.000}{100} = 1.804.000

<u>1.804.000 cockroaches are immune.</u>
