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