### Text of Objective: I can solve problems using ratios and proportions

Pre-Algebra Ch 8-5 Lesson # 2

Objective: I can solve problems using ratios and proportions.

Objective1 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 1/8th of his size. We will explore whether this was really true, or Hollywood Lies.

Dr. Evil and Mini-Me

2What is the problem you need to solve?

Ex: We need to figure out whether or not Mini-Me was really 1/8th of Dr. Evils size according to his weight and height

Problem Solving

3 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. EvilThe height of Dr. EvilThe weight of Dr. Evil

Problem Solving

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

Height - Dr. Evil and Mini-Me

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

Weight - Dr. Evil and Mini-Me

6How tall would Mini-Me have to be for him to be 1/8th of Dr. Evils Height?

How much would Mini-Me have be for him to be 1/8th of Dr. Evils Weight?

In your opinion, based off of our results, how would you describe the notion that Mini-Me is 1/8th of Dr. Evils size?
