Question #9

Friday, November 27, 2009
HI, EVERYONE !! Today I'm going to try and explain question #9 from the textbook.

Problem:
Lori owed her mother $39. Lori paid back 1/3 of this debt and then paid back 1/4 of the remaining debt.

Question:
How much does Lori still owe her mother ?


It says here that Lori paid her mother back 1/3 of $39. Now, let's find out what 1/3 of $39.

39/1 x 1/3 = $13 So she paid $13 and she still owes 2/3 of $39.
So, we have to find out what 2/3 and here's how you find it, 39 - 13 = $26. She still owes her mom $26.


So, now its says here that she paid 1/4 of the remaining debt. Now, let's find out what 1/4 of $26.

26/1 x 1/4 = 6.50 She paid back $6.50 from $26. And she still owes 3/4. Now let's find out what 3/4 is. So you have to subtract $6.50 from $26 and this is how you do it, 26 - 6.50= $19.50.


So, Lori still owes her mother $19.50 .

I guess that's it. I hope you guys understand it :D PLEASE COMMENT ON MY MISTAKES !! Thank you for reading my post :)

Hi Krissia! Your post is really good! The only mistakes I found were the "dept" having to be "debt" and "Still" has to be lower case. It's under the question header. Great job, Krissia!

Good Job Krissia. Other than the mistakes Mr. B and Linda pointed out there's nothing else. You explained it very well and It wasn't confusing at all.
