Answer:

50 total penguins

Step-by-step explanation:

In the following example x = the total number of penguins.

Set it up as follows.

15 over x = 30 over 100

Cross multiply the numbers. (30 times x) and (15 times 100)

This results in 30x = 1500.

Divide both sides by 30 which results in x = 50.

This means that there is a total of 50 penguins.

In the following example x = the number of Emperor penguins.

If you would like to double check this, set up as follows.

x over 50 = 30 over 100

Cross multiply the numbers. (30 times 50) (100 times x)

This results in 100x = 1500.

Divide both sides by 100 which results in x =1 5.

This means that there are 15 Emperor penguins.
