A \(\frac{9}{{11}} ; \frac{1}{{25}} ; \frac{{ 1}}{{25}} ; \frac{{ - 1}}{{25}}\)

B \(\frac{-9}{{11}} ; \frac{1}{{25}} ; \frac{{ - 1}}{{25}} ; \frac{{ - 1}}{{25}}\)

C \(\frac{9}{{11}} ; \frac{1}{{25}} ; \frac{{ - 1}}{{25}} ; \frac{{ - 1}}{{25}}\)

D \(\frac{9}{{-11}} ; \frac{1}{{25}} ; \frac{{ - 1}}{{25}} ; \frac{{ - 1}}{{25}}\)

A \(\frac{2}{{ - 50}} = \frac{{ - 9}}{{225}}\)

B \(\frac{27}{{ 33}} = \frac{{ - 9}}{{225}}\)

C \(\frac{27}{{ 33}} = \frac{{ - 25}}{{-625}}\)

D \(\frac{-2}{{ 50}} = \frac{{ - 25}}{{-625}}\)

A \(\frac{{-25}}{{-625}} = \frac{{ - 88}}{{ - 121}}\).

B \(\frac{{-25}}{{-625}} > \frac{{ - 88}}{{ - 121}}\).

C \(\frac{{27}}{{33}} = \frac{{ - 88}}{{ - 121}}\).

D \(\frac{{27}}{{33}} > \frac{{ - 88}}{{ - 121}}\).
