At 1am, my son got hungry and ate $\frac{1}{5}$ of it.

At 2am, my daughter got hungry and ate $\frac{1}{4}$ of what was left.

At 3am, my wife got hungry and ate $\frac{1}{3}$ of what was left.

At 4am, my dog got hungry and ate $\frac{1}{2}$ of what was left.

What percentage of the pie (in %) was left for me in the morning?
