I assume by smallest number, you're really looking for the smallest *positive* number.

Notice that -5 fits all these requirements:

-5\equiv15\mod20
-5\equiv20\mod25
-5\equiv25\mod30
-5\equiv31\mod36
-5\equiv43\mod48

Any number of the form -5+nk will also satisfy these conditions, where k\in\mathbb Z and n is the least common multiple of the moduli. You have

\mathrm{lcm}(20,25,30,36,48)=3600

so the least positive number would be achieved with k=1, giving 3595 as the answer. (Verified with a script.)

A fish dives into a depth of -3/4 mile below the surface of the water. A turtle's depth is 1/3 as deep as the fish's depth. What
Tomtit [17]
Basically you just need to multiply the two fractions together to get the depth of the turtle. Therefore the turtle is 3/12 miles deep or 1/4 mile deep.
