Confused? Don't be!!! Proprotions are easy once you understand them. :) Let's take a math problem:
A baby giraffe casts a 3.2-foot shadow and an adult giraffe casts a 8-foot shadow. The adult is 15 feet tall.
The easiest way is to think this: Put the shadow heights over the height of the giraffe. So the proportion is:
3.2/x = 8/15 Cross multiply. (3.2 x 15) equals 48. (8 x (x) ) equals 8x.
48 divided by 8 equals 6. 6 is the answer!!! :) now u are set for solving
