Question

In a nature conservatory, the ratio of butterflies to total number of flying insects is 36 to 100. There are 450 total flying insects

Answer 1

Cross multiply
(36/100) = (x/450)
Multiply 36 by 450
That gives you 16,200.
Then divide 16,200 by 100.
The total number of butterflies is 162.

(36/100) = .36
(162/450) = .36
