In a laboratory there are 40 fruitflies last week and during experiment 4 fruitflies died in a week. Calculate the death rate.

If 4 individuals in a laboratory population of 40 fruitflies died during a specified time interval (i.e., a week), the death rate in the population during that period is

If 8 individuals in a laboratory population of 80 fruit flies died in a week, then what would be the death rate for population for the said period ?

If 8 individuals in a laboratory population of 80 fruit flies died in a week, then what would be the death rate for population for the said period ?
