$2 \frac{1}{2} x \: 4 \frac{3}{10} x \: \frac{3}{10}$

$2\frac{1}{2} = \frac{5}{2} \: \: \: \: \: \: \: \: \: 4\frac{3}{10} = \frac{43}{10}$

$2 \frac{1}{2} x \: 4 \frac{3}{10} x \: \frac{3}{10} = \frac{5}{2} x \frac{43}{10}$

$\frac{5}{2} \: x \: \frac{43}{10} \: x \: \frac{3}{20} = \frac{645}{400}$
