$\frac{1}{5}$ is invested in bonds.
This problem can be restated to say that $\frac{1}{3}$ of $\frac{3}{5}$ of the investments are in bonds. Multiply to determine the fraction that are in bonds. $\frac{1}{3} \times \frac{3}{5}$ can be reduced by the common factor of 3. $\frac{1}{1} \times \frac{1}{5} = \frac{1}{5}$
