When he is making "hours" the denominator, he also has to make the numerator 3600 "seconds" to keep the value same as before, since (3600 sec)/1h = 1 and multiplying any number (except 0) by 1 will always be the number you multiplied to, meaning it wouldn't change the value. These quizzes pair perfectly with my PowerPoint and Guided Notes. mc027-1.jpg Includes short answer questions on math with significant figures and dimensional analysis.
