In today’s MathStratChat, Pam and Kim discuss the MathStratChat problem shared on social media on June 28, 2023. 

Note: It’s more fun if you try to solve the problem, share it on social media, comment on others strategies, before you listen to Pam and Kim’s strategies.

Pam  00:01

Hey, fellow mathematicians. Welcome to our podcast where math is Figure-Out-Able. I'm Pam. 


Kim  00:07

And I'm Kim. 


Pam  00:08

And this is a MathStratChat episode where we chat about math strategies. Every Wednesday, I throw out a math problem on Twitter, Facebook, and Instagram, all the social media and people from around the world chat about the strategies they use. It's super to hear everyone's thinking.


Kim  00:25

So, this past Wednesday, our problem was 36 is 8% of what? How would you solve this problem? Pause the podcast and solve the problem any way you want. The problem is 36 is 8% of what? Solve it, and then come on back to here how we solve it.


Pam  00:42

Alright, I'm going first today. 


Kim  00:43

Okie dokie. 


Pam  00:44

I'm just calling it. Okay, I'm looking at 36 in relation to 8% on a percent bar, and I'm saying to myself, "Can I scale from 8% to 100%?" Not very easily. But I think I could scale from 8% to... Oh, I could go to 2 or I could go to 4. I'm going to go to 4. No, I'm going to go 2... Oh, either one. I'm going to go to 2. So, I'm going to go to 2%, which means I divided by 4. So, I'm going to divide the 36 by 4, and that's 9. So, I scale the 2 times 50 to get to 100%. So, I'm going to scale the 9 times 50. And 9 times 5 is 45. So, it would be 450. So, 36 is 8% of 450.


Kim  01:25



Pam  01:26

Is that okay?


Kim  01:26

I like it. Yeah.


Pam  01:27

What do you do? 


Kim  01:30

You know, I've been on this kick of the...


Pam  01:32

Not again! 


Kim  01:33



Pam  01:34

I mean, do it, do it!


Kim  01:36

Okay. So, 36 and 8. 36 and 8 to me are not amazing. But 32 and 8 are. So, if it were 32 and 8, then that would be times 4. 8 times 4 is 32.


Pam  01:52

Yes, yes. 


Kim  01:54

So, 36 would be 4 and a 1/2. So, there's a relationship of 36 and 8, which is times 4 and a 1/2. 


Pam  02:02



Kim  02:03

So, then, if it were 4 and a 1/2, and I was scaling up to the 100, then it would be 450.


Pam  02:15

Nice. So, how did you get... You sort of scaled. How do I get from 8 to 36? Was times 4 and a 1/2. So, then 100 times 4 and a 1/2 is 450. Nice. I like it. I like it. Well done. I can't wait to see what everybody else is doing with this problem.


Kim  02:30

Yeah, me too. I wonder if your strategy was like one of ours. Represent your thinking, take a picture of your work or screenshot on your phone, and tell the world on social media. And while you're there posting your thinking, check out what other people did and comment on their's. 


Pam  02:44

Yeah, it's super fun to hear. And people love it when they're like, "Oh, somebody liked my strategy." 


Kim  02:49

Yes! Absolutely.


Pam  02:49
