Show that given ratio are in proportion
$7.5 l i t r e s : 15 l i t r e s = 5 k g : 10 k g$
$99 k g : 45 k g = r s 44 : r s 20$
$32 m : 64 m = 6 s e c : 12 s e c$

Solution

Condition for $a : b = c : d$

to be in Proportion is $a d = b c$

$7.5 : 15 = 5 : 10$

$7.5 (10) = 5 (15)$

$75 = 75$

They are in Proportion.

$99 : 45 = 44 : 20$

$99 (20) = 45 (44)$

$1980 = 1980$

They are in proportion.

$32 : 64 = 6 : 12$

$32 (12) = 6 (64)$

$384 = 384$

They are in proportion.
