   Examiner

   Hey there, I'm professor Foster Provost from NYU Stern. I am ready to conduct your exam today. Am I speaking to [DEMO STUDENT]? Can you please tell me your name and your NET ID?

2. 0:13
   Caller

   Yeah, my name is Konstantin.

3. 0:18
   Examiner

   Thanks, Konstantin. What is your Net ID?

4. 0:21
   Caller

   K-R-888.

5. 0:25
   Examiner

   Great, hello [DEMO STUDENT]. I see your Net ID matches. I also see you worked on Team B. Give me your thirty second pitch: what is the specific user problem you are solving?

6. 0:39
   Caller

   Okay, so I'm working on dividing fractions. In particular, I have this question, 8 sevenths divided by 16 fifteenths.

7. 0:54
   Examiner

   So you are solving the user problem of dividing fractions, brave choice for Team B, very Pied Piper of you. What is eight sevenths divided by sixteen fifteenths?

8. 1:08
   Caller

   Well, I don't know

9. 1:09
   Examiner

   Fair. When you divide by a fraction, what operation do you do with the second fraction?

10. 1:21
    Caller

    You flip it

11. 1:23
    Examiner

    Good. After you flip sixteen fifteenths, what fraction do you multiply eight sevenths by?

12. 1:34
    Caller

    I'm not sure.

13. 1:37
    Examiner

    If you flip sixteen fifteenths, what do you get?

14. 1:41
    Caller

    15 sixteenths.

15. 1:45
    Examiner

    Great. Now multiply eight sevenths by fifteen sixteenths and simplify; what do you get?

16. 1:52
    Caller

    How does it work? Why do I flip it and that works?

17. 1:56
    Examiner

    Because division by a number means multiply by its reciprocal, since a fraction times its reciprocal equals one, and multiplying by one does not change the value. What is eight times fifteen over seven times sixteen, simplified?

18. 2:14
    Caller

    Simplify this and give me examples, spell it out slowly.

19. 2:20
    Examiner

    Eight sevenths divided by sixteen fifteenths means eight sevenths times the reciprocal of sixteen fifteenths. The reciprocal is fifteen sixteenths, because sixteen fifteenths times fifteen sixteenths equals one. So compute eight sevenths times fifteen sixteenths. Multiply across to get one hundred twenty over one hundred twelve. Simplify by dividing top and bottom by eight to get fifteen fourteenths. What is one other fraction division you want to try, and I will walk you through it the same way?

20. 2:53
    Caller

    You give me an example.

21. 2:56
    Examiner

    Try this one: three fourths divided by two thirds. You flip the second fraction to get three halves, then multiply: three fourths times three halves equals nine eighths, which is one and one eighth. What...

22. 3:07
    Caller

    Can you speak slower and go through each step slower?

23. 3:13
    Examiner

    Okay. Example: three fourths divided by two thirds. Step one: keep the first fraction the same, three fourths. Step two: division means multiply by the reciprocal of the second fraction. Step three: the...

24. 3:25
    Caller

    Are you capable of going slower and talking in slow steps and asking me after each step if I understand?

25. 3:36
    Examiner

    Yes. Step one: we start with the problem three fourths divided by two thirds, and we keep the first fraction as three fourths. Do you understand step one?

26. 3:49
    Caller

    Yes.

27. 3:51
    Examiner

    Step two: change the division sign into multiplication, because dividing by a fraction is the same as multiplying by its reciprocal. Do you understand step two?

28. 4:04
    Caller

    I think so.

29. 4:07
    Examiner

    Step three: take the second fraction, two thirds, and flip it to get its reciprocal, three halves. Do you understand step three?

30. 4:16
    Caller

    Yes.

31. 4:18
    Examiner

    Step four: now multiply the fractions: three fourths times three halves. Multiply the tops: three times three equals nine. Multiply the bottoms: four times two equals eight. So the result is nine eighths. Do you understand step four?

32. 4:36
    Caller

    Yeah okay.

33. 4:39
    Examiner

    Step five: if you want it as a mixed number, nine eighths equals one and one eighth, because eight eighths is one whole and one eighth is left over. Do you understand step five?

34. 4:55
    Caller

    Sure.

35. 4:58
    Examiner

    Good. Now go back to your original problem: eight sevenths divided by sixteen fifteenths. What is the reciprocal of sixteen fifteenths?

36. 5:11
    Caller

    Fifteen sixteenths.

37. 5:14
    Examiner

    Great. Now multiply: eight sevenths times fifteen sixteenths. What do you get after simplifying?

38. 5:23
    Caller

    Can you walk me through that solution?

39. 5:27
    Examiner

    Step one: rewrite the problem as multiplication by the reciprocal: eight sevenths times fifteen sixteenths. Do you understand step one?
