Answer:
1.1mg will be given per cockroach
Explanation:
From the problem, we can see that 55mg was given per kilogram of cockroach.
We can set up a simple relation in determining the dose per mg in each cockroach.
55 mg was given to 1 kg or roaches
x kg will be given to 0.02kg of roaches
x = (0.02 X 55) / 1
x = 1.1mg
therefore 1.1mg will be given per roach
Explanation:
