$\displaystyle \frac{2}{5} = \frac{5}{15}$

$\displaystyle \frac{2}{15} = \frac{6}{5}$

$\displaystyle \frac{2}{6} = \frac{5}{15}$

$\displaystyle \frac{2}{5} = \frac{15}{6}$

$\displaystyle x = \frac{16.4}{5}$

$\displaystyle x = \frac{16.5}{4}$

$\displaystyle x = \frac{5.4}{16}$

$\displaystyle x = \frac{4}{16.5}$

$\displaystyle x : y = a : b$

$\displaystyle x : y = b : a$

$\displaystyle x . y = a : b$

$\displaystyle x : y = a . b$

$\displaystyle \frac{a}{4} = \frac{b}{3} = \frac{c}{5}$

$\displaystyle \frac{a}{5} = \frac{b}{3} = \frac{c}{4}$

$\displaystyle \frac{a}{4} = \frac{b}{5} = \frac{c}{3}$

$\displaystyle \frac{a}{3} = \frac{b}{4} = \frac{c}{5}$

$\displaystyle \hat{B} < \hat{A}$

$\displaystyle \Delta ABC = \Delta MNP (g.c.g);$

$\displaystyle \Delta ABC = \Delta MNP (c.c.c);$

$\displaystyle \Delta ABC = \Delta MNP (c.g.c);$

$\displaystyle \Delta CAB = \Delta MNP (c.c.c)$

$\displaystyle AD = AB$
