Answer
$ 100 \cdot \frac{21}{50} \cdot \frac{3}{4} = \frac{63}{2} $
Work Step by Step
$ 100 \cdot \frac{21}{50} \cdot \frac{3}{4} = \frac{100}{1} \cdot \frac{21}{50} \cdot \frac{3}{4} = \frac{2}{1} \cdot \frac{21}{1} \cdot \frac{3}{4} = \frac{1}{1} \cdot \frac{21}{1} \cdot \frac{3}{2} = \frac{21 \cdot 3}{2} = \frac{63}{2} $
