Question

Is the answer 200? Or 4.5??? Or is none ? I don't know it's confusing :/ can I get help :/

Answer 1

Let x = the number of penguins we are finding

x ÷ 100 × 30 = 15
x = 15 ÷ 30 × 100
x = 50

hope this helps and have a great day :)

Answer 2

15 emperor penguins = 30% of the Penguins at the zoo
5 emperor penguins = 10% of the Penguins at the zoo
So 15x3= 45 which also equals 90% so add 5 penguins and you get 100%
50 penguins live in the zoo
50 penguins = 100%
Hope this helps :3
