Question

there are over 2700 species of snakes in the world. over 600 species are venomous. write the fraction of species that are not venomous as a decimal.

Answer 1

0.77

Step-by-step explanation:

There are over 2700 species of snakes in the world.

Over 600 species are venomous.

Since there are 600 species that are venomous, there are 2700-600=2100 that are not venomous.

i.e. 2100/2700 = 7/9

= 0.77 are non-venomous

Answer 2

The answer is 0.7777... (0.7 repeating).

Step-by-step explanation:
Since there are 600 species that are venomous, there are 2700-600=2100 that are not venomous.

This is out of 2700 species; 2100/2700 = 7/9. Dividing 7 by 9, we get the decimal 0.7 repeating.
