Question

There are 400 types of poisonous snakes in the world. Given that this number represents 13 1/3% of the total number of snake varieties, how many varieties are there in the world?

Answer 1

Well you could do proportions
\[\frac{ 400 }{ x }=\frac{ 13.333 }{ 100 }\]Then cross multiply
\[40000=13\frac{ 1 }{ 3 }x\]Then divide by 13 1/3 to get x or total varieties of species
\[x=3000\]
