Eduardo is 6 feet tall and casts a 12-foot shadow. At the same time, Diane casts an 11-foot shadow. How tall is Diane?
Lovely proportions. This is how you'd solve:
$${\frac{{\mathtt{6}}}{{\mathtt{12}}}} = {\frac{{\mathtt{n}}}{{\mathtt{11}}}}$$ The numbers in the denominators are the length of the shadows the two individuals produce. The numbers in the numerator represent the acutal height of the individuals, hence, n represents Diane's height. (Remember when setting up the equation not to mix up the numbers. All the numbers that refer to Eduardo must be on one side of the equation. All numbers referring to Diane must go on the other)We'd then use the "fishy" method. (That's what my math teacher called it, as if you draw a line over the order in which you solve the question, you get a picture that resembles a fish.) You start by mulitplying the 6 and the 12 together, making 66. You'd then divide that product by 12. The result is your answer!
Hope this helps and good luck!
