22.5

Explanation:

The ratio of parrot fish to clownfish is 4:3. He saw 30 parrot fish. Therefore, we can write a fraction like this:
$\frac{4}{3}$ $4/3$ = $\frac{30}{c}$ $30/c$
where c is the number of clownfish.
This simplies to:
$4 \cdot c = 3 \cdot 30$ $4*c=3*30$

$4 c = 90$ $4c=90$

$c = \frac{90}{4}$ $c=90/4$

$c = 22.5$ $c=22.5$ clownfish

Hope this helps!
