Question

The ratio of parrot fish to clown fish is 4:3, He saw 20 parrot fish, how many clownfish did he see?

Answer 1

He saw 15 clown fish.

Explanation:

So let start off with a fraction to understand this problem easily.

`"4 parrot fish"/"3 clown fish"`

Now, let make a ratio equation.

`"4 parrot fish"/"3 clown fish"` = `"20 parrot fish"/"x clown fish"`

Now, we have a proportion. SO you cross multiple and you end up with

60 = 4x

Divide both side by 4 and you get 15.
