The ratio of North American butterflies to South American butterflies at a butterfly park is 5:3. There are 30 North American butterflies at the butterfly park. How many South American butterflies are there?

What does 6 stand for?

To find the number of South American butterflies at the butterfly park, we need to use the given ratio of North American butterflies to South American butterflies.

The ratio of North American butterflies to South American butterflies is 5:3. This means that for every 5 North American butterflies, there are 3 South American butterflies.

We are given that there are 30 North American butterflies at the butterfly park. To find the number of South American butterflies, we can set up a proportion:

North American butterflies / South American butterflies = 5 / 3

Substituting the given values:

30 / South American butterflies = 5 / 3

To solve for the number of South American butterflies, we can cross-multiply:

30 * 3 = 5 * South American butterflies

90 = 5 * South American butterflies

Now, divide both sides by 5 to isolate the variable:

90 / 5 = South American butterflies

South American butterflies = 18

Therefore, there are 18 South American butterflies at the butterfly park.

for every 5 NA butterflies, there are 3 SA.

30/5 = 6, so there are 6*3=18 SA butterflies.
