$\frac{354}{438} = \frac{3 * 118}{3 * 146} = \frac{118}{146} = \frac{2 * 59}{2 * 73} = \frac{59}{73}$
$\frac{1710}{1860} = \frac{171}{186} = \frac{3 * 57}{3 * 62} = \frac{57}{62}$
$\frac{216}{324} = \frac{4 * 54}{4 * 81} = \frac{54}{81} = \frac{6}{9} = \frac{2}{3}$
$\frac{345}{465} = \frac{5 * 69}{5 * 93} = \frac{69}{93} = \frac{3 * 23}{3 * 31} = \frac{23}{31}$
$\frac{2250}{3105} = \frac{5 * 450}{5 * 621} = \frac{450}{621} = \frac{9 * 50}{9 * 69} = \frac{50}{69}$
$\frac{270}{360} = \frac{27}{36} = \frac{3}{4}$
$\frac{108}{135} = \frac{9 * 12}{9 * 15} = \frac{12}{15} = \frac{4}{5}$
$\frac{222}{246} = \frac{2 * 111}{2 * 123} = \frac{111}{123} = \frac{3 * 37}{3 * 41} = \frac{37}{41}$
$\frac{144}{243} = \frac{9 * 16}{9 * 27} = \frac{16}{27}$
$\frac{225}{450} = \frac{9 * 25}{9 * 50} = \frac{25}{50} = \frac{1}{2}$
