Question

Suppose that there are 67 butterfly species for every 22,000 insect species and there are 15,000 to 22,000 species of butterflies worldwide. how many insect species are there

Answer 1

There are 4,925,250 to 7,223,700 insect species worldwide.

Explanation:

Supposing that there are 67 butterfly species for every 22,000 insect species and there are 15,000 to 22,000 species of butterflies worldwide, in order to know how many insect species are there we have to do the following calculation:

22,000 (insect species) / 67 (butterfly species) = X (relation of butterfly and insect species)

22,000 / 67 = X

328.35 = X

There are 328.35 insect species for every butterfly species.

So, as there are 15,000 to 22,000 species worlwide, we have to multiply those numbers by 328.35 to know the total amount of insect species:

15,000 x 328.35 = 4,925,250

22,000 x 328.35 = 7,223,700

There are 4,925,250 to 7,223,700 insect species worldwide.

Answer 2

we know that

for 15000 species of butterflies
if there are 67 butterfly species for every -------------> 22,000 insect species
for 15000 species of butterflies-------------------------------> X
X=15000*22000/67---------> X=4925373.13 insect species

for 22000 species of butterflies
if there are 67 butterfly species for every -------------> 22,000 insect species
for 22000 species of butterflies-------------------------------> X
X=22000*22000/67---------> X=7223880.60 insect species

the answer is
there are 4925373 to 7223881 insect species
