Country

\mathcal{A}

has

c\%

of the world's population and owns

d\%

of the world's wealth. Country

\mathcal{B}

has

e\%

of the world's population and

f\%

of its wealth. Assume that the citizens of

\mathcal{A}

share the wealth of

\mathcal{A}

equally, and assume that those of

\mathcal{B}

share the wealth of

\mathcal{B}

equally. Find the ratio of the wealth of a citizen of

\mathcal{A}

to the wealth of a citizen of

\mathcal{B}
