## Math is Figure-Out-Able!

# #MathStratChat - September 25, 2024

In today’s MathStratChat, Pam and Kim discuss the MathStratChat problem shared on social media on September 25, 2024.

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.

Hey, fellow mathers! Welcome to the podcast where Math is Figure-Out-Able. I'm Pam.

**Kim **00:06

And I'm Kim.

**Pam **00:06

And this episode is a MathStratChat episode where we chat about our math strategies. Every week, I throw out a math problem on social media, and people from around the world chat about the strategies they use and comment on each other's thinking. We love it when you comment on each other's thinking.

**Kim **00:21

Yeah, I enjoy scrolling through those and like just I smile. Okay, so this Wednesday, our math problem was 49% of 25. And we're curious, how will you solve this problem? Pause the podcast, solve however you'd like, and then come on back to hear how we solve the problem. The problem is 49% of 25.

**Pam **00:40

Dun, dun, dun. Okay, I'm going to use the commutative property,

**Kim **00:44

Okie doke.

**Pam **00:45

Of multiplication. And so, I'm going to think about 49% 25 as 25% of 49. But to think about 25%, or a fourth, one-fourth of 49, I'm going to think about a fourth of 48.

**Kim **01:01

Okay.

**Pam **01:02

So, a fourth of 48, I believe, is 12 because 4 times 12... Is that right? Fourth of 48.

**Kim **01:10

Mmhm.

**Pam **01:11

Yes. Is 12. I had think about that. I'm thinking a little tired today. So, if a fourth of 48 is 12, I still need a fourth of one more. And a fourth of 1 is a fourth. Or 0.25. And so, then I would add those two together, and I would get 12 and a 1/4, 12.25.

**Kim **01:29

Nice.

**Pam **01:29

What you got?

**Kim **01:31

Well, last week I want to do Over, and I didn't, so I'm going to do over this time. And so, instead of thinking about 49% of 25, I'm going to think about 50% of 25.

**Pam **01:40

Okay.

**Kim **01:40

And 50% of 25 is 12.5.

**Pam **01:45

Sure.

**Kim **01:46

And then, I'm going to do 1% of 25. And 100% of 25 is 25, so 10% is 2.5, so 1% is 0.25. Which makes me think of a quarter. So, 50% was like $12.50, 1% is like a $0.25. So, $12.50 minus a $0.25 is 12.25.

**Pam **02:13

Bam.

**Kim **02:14

Yeah.

**Pam **02:14

Nicely done. Very good. Alright.

**Kim **02:17

Alright, we can't wait to see what you guys do every single week on the podcast... On the podcast. On MathStratChat. Let us know how you think about the problems. And while you're there, comment on each other's strategies. Super fun.

**Pam **02:29

(unclear).

**Both Pam and Kim **02:29

Yeah.

**Pam **02:29

We post the problems on Wednesdays at 7:00 pm Central time. When you answer, tag me and use the hashtag MathStratChat. Then join us here to hear how we're thinking about the problem. We love having you as part of the Math is Figure-Out-Able movement because Math is Figure-Out-Able!
