Are $12, 18, 8, 12$ in proportion?
True
False

$12, 18, 8, 12$

(To determine whether they are in proportion)

If $\frac{a}{b} = \frac{c}{d}$ [No are said to be in proportion]

$\frac{a}{b} = \frac{12}{18} = \frac{2}{3}$

$\frac{c}{d} = \frac{8}{12} = \frac{2}{3}$

since, $\frac{a}{b} = \frac{c}{d}$

They are in proportion.
