To fill in the blanks for the equation \( \frac{1}{5} = \frac{?}{15} \), you can use cross-multiplication or set up a proportion.

Set up the proportion:

\[ 1 \times 15 = 5 \times ? \]

This simplifies to:

\[ 15 = 5 \times ? \]

Now, divide both sides by 5:

\[ ? = \frac{15}{5} = 3 \]

So, the completed equation is:

\[ \frac{1}{5} = \frac{3}{15} \]

Thus, the blank should be filled with 3.
