first you would do 2700-600. Then you would put that answer which is 2100, over 2700(2100/2700) then divide that.(2100 divided by 2700). then your answer wold be .77 repeating.

Answer:

The fraction of species that are not venomous to the total number of snakes is 0.78

Explanation:

Total number of species of snakes in the world = 2,700

Total number of venomous species of snakes in the world = 600

So subtracting the number of venomous species from number of species of snakes will give the number of non venomous species.

Hence,


\text{Number non venomous species}=2700-600=2100

The fraction of species that are not venomous is,


=\frac{\text{Number non venomous species}}{\text{Total number of species}}

Putting the values,


=(2100)/(2700)=0.7777....\approx 0.78
