a/b = c/d
ad = bc
1/4 = 2/8
(1)(8) = (2)(4)
8 = 8
They're equal.
ad = bc
1/4 = 2/8
(1)(8) = (2)(4)
8 = 8
They're equal.

When you cross multiply two equal ratios, the cross products are EQUAL.
Example:
2/3 = 4/6
Cross products:
2 * 6 = 3 * 4
12 = 12
Example:
2/3 = 4/6
Cross products:
2 * 6 = 3 * 4
12 = 12

equal, because the product of the means equals the product of the extremes.
