21% reptiles, 11% are birds. There are a total of 1,500 animals in the zoo. Is this the correct proportion that I wrote to solve?


11/21 = r/1,500

What is the question you want to solve?

Answered by moby
hi Ms. Sue.

It is not to solve but how I am suppose to write out to solve.
the choices were;

11/21 = r 1,500 ***** this is the one I chose.


11/100 = r /1,500
21/100 = r/1,500
Answered by moby

Answered by Ms. Sue
Do you want to know how many reptiles? Or how many birds? Or something else?

In a zoo, 21%of the animals are reptiles, 11% are birds. There are a total of 1,500 animals in the zoo. Which proportion can be solved for r, the number of reptiles in the zoo.

Is this the correct proportion that I wrote to solve?


11/21 = r/1,500 I chose. :)

Yes Moby that is the opposite. Remember the opposite or any number has a - except 0.
