1 15/16 + 3 7/24 + 3 11/12 = ??? I got 8 33/48 as my answer. Is that correct? If it isnt can you show your work please

OpenStudy (phi):

48 is the correct denominator to use. But you made a mistake somewheres...

OpenStudy (mathhelp346):

Can you show me how you got your answer? Did you solve the problem?

OpenStudy (phi):

can you change 15/16 to something/48 ?

OpenStudy (mathhelp346):

yea 1 45/48

OpenStudy (phi):

and 7/24 --> ??/48

OpenStudy (phi):

and 11/12 --> ??/48

OpenStudy (mathhelp346):

3 7/24 --> 3 14/48

OpenStudy (mathhelp346):

3 11/12 --> 3 22/48

OpenStudy (phi):

looks good. add the whole numbers and set them aside for the moment

OpenStudy (phi):

add the fractions

OpenStudy (mathhelp346):

12 92/48

OpenStudy (phi):

(45+14+22)/48 = ??

OpenStudy (mathhelp346):

I don't get it..

OpenStudy (mathhelp346):

???

OpenStudy (phi):

oops the last fraction 11/12 --> 4*11/4*12 = 44/48

OpenStudy (mathhelp346):

?

OpenStudy (phi):

so we add (45+14+44)/48

OpenStudy (mathhelp346):

where did you get the 44?

OpenStudy (phi):

You did 3 11/12 --> 3 22/48 but that is not right.

OpenStudy (mathhelp346):

so which is the right one

OpenStudy (mathhelp346):

3 11/12 --> ??/48

OpenStudy (phi):

you multiply top and bottom by 4

OpenStudy (mathhelp346):

why?

OpenStudy (phi):

can you change 11/12 --> something/48 ?

OpenStudy (mathhelp346):

yea wouldn't it be 22/48 ?

OpenStudy (mathhelp346):

OH i get it now

OpenStudy (phi):

OpenStudy (mathhelp346):
