Proportions This PowerPoint was made to teach primarily 8th grade students proportions. This was in response to a DLC request (No. 228).

Proportions  A proportion is an equation with a ratio on each side. It is a statement that two ratios are equal.  3 = 6 is an example of a proportion.

Direct Variation: y varies directly as x (y is directly proportional to x), if there is a nonzero constant k such th at 3.7 – Variation The number k is.

Objective: I can solve problems using ratios and proportions.

In the movie Austin Powers 2, there was a clone created of Dr. Evil named Mini-Me. Mini-me was similar to Dr. Evil in every single way, except according to the movie producers, he was 1/8 th of his size. We will explore whether this was really true, or Hollywood Lies.

What is the problem you need to solve? Ex: – We need to figure out whether or not Mini-Me was really 1/8 th of Dr. Evil’s size according to his weight and height

What mathematical information do we need to know so we can solve this problem? Ex: – Whether we are referring to the Height or Weight of Dr. Evil – The height of Dr. Evil – The weight of Dr. Evil

Let’s assume that Dr. Evils is 5ft 10 inches tall. How tall would Mini-me have to be in order for the statement of being 1/8 th his size to be true?

Let’s assume that Dr. Evil weighs 200 pounds. How much would Mini-Me have to weigh in order for the statement of being 1/8 th his size to be true?

1.How tall would Mini-Me have to be for him to be 1/8 th of Dr. Evil’s Height? 2.How much would Mini-Me have be for him to be 1/8 th of Dr. Evil’s Weight? 3. In your opinion, based off of our results, how would you describe the notion that Mini-Me is 1/8 th of Dr. Evil’s size? 4.What did you learn today?
