Determine if the following are in proportion
(a) 4,6,8,12
(b) 33,121,9,96
Solution:
(a) 4,6,8,12
$\frac{4}{6} = \frac{8}{12}$ is true so 4, 6, 8, 12 are in proportion.
(b) 33,121,9,96
$\frac{33}{121} = \frac{3}{11}$
$\frac{9}{96} = \frac{3}{32}$
So $\frac{33}{121} ≠ \frac{9}{96}$
So 33, 121, 9, 96 are NOT in proportion.
