2,700-600=2,100(not venomous)
2100/2700 is the fraction that aren't venomous.
in decimal form, it is .77777777777777 (and so on. you can round it to .7, .77, or .777 if you'd like)
2,700-600=2,100

your fraction is 2,100/2,700 that are not venomous 

2,100÷2,700=0.777777778

2,100/2,700 as a decimal is 0.777777778

you could round this to .778

hope this helped a little
