OpenStudy (anonymous):

@luckycoins888 We need to change the mixed number into an improper fraction.

OpenStudy (anonymous):

So multiply the denominator x the whole number. So what is 3 x 5?

OpenStudy (luckycoins888):

thanks i get it now you helped alot cuz this whole test is full of that stuff

OpenStudy (anonymous):

No.

OpenStudy (anonymous):

That's wrong.

OpenStudy (anonymous):

We have to change the mixed number into an improper fraction first. Can you do that?

OpenStudy (anonymous):

@luckycoins888 You know how to change a mixed number into an improper fraction, right?

OpenStudy (luckycoins888):

15

OpenStudy (luckycoins888):

OpenStudy (luckycoins888):

no

OpenStudy (luckycoins888):

i dont

OpenStudy (anonymous):

Ok, so you multiplied 3 x 5 to get 15. So add 15 to the numerator, which is 2. 15 + 2 = ?

OpenStudy (luckycoins888):

oh its 10/3 right?

OpenStudy (luckycoins888):

17

OpenStudy (anonymous):

No...

OpenStudy (anonymous):

Yes, 17 is the numerator, and you keep the same denominator in the mixed number, so what is the improper fraction?

OpenStudy (luckycoins888):

10/3?

OpenStudy (anonymous):

No....

OpenStudy (anonymous):

17 is the numerator, not 10.

OpenStudy (luckycoins888):

OpenStudy (anonymous):

So your fraction is...?

OpenStudy (luckycoins888):

17/3

OpenStudy (anonymous):

Yes.

OpenStudy (luckycoins888):

thanks alot

OpenStudy (anonymous):

And you have to find the reciprocal of the improper fraction

OpenStudy (luckycoins888):

:-D

OpenStudy (anonymous):

By flipping it over.

OpenStudy (luckycoins888):
