Question

Of all the species in the world, 4 out of every 5 are insects. What percentage of species are insects?

Answer 1

80%

Explanation:

Bugs are 4/5, but you can't do that as a precentage. You then multiply 5 x 2 to get 10, and 4 x 2 to get 8. Then, you multiply both by 10, and then you take out the fraction and replace it with a precent sign. Then you get your answer, 80%.
