Question

An 8in x 11in photo is enlatged by 200% what are the Dimensions of the enlargement?

Answer 1

16in x 22in

Explanation:
8in = 100%
x = 200%
(200*8) / 100 = 16

11in = 100%
X = 200%
(200*11) / 200 = 22

The trick is to cross multiply (without multiplying the X) and then divide by the number that was not multiplied :)

Additional comment

The factor 200% is equal to 200/100 = 2. (% and /100 are interchangeable)
