OpenStudy (abbie):

ok

OpenStudy (abbie):

and the other id 378/21

OpenStudy (abbie):

oh ok I had to simplify

OpenStudy (agent0smith):

Why not add together the whole numbers, THEN add together the fractions? it'll keep things much smaller and simpler.

OpenStudy (agent0smith):

\[\large 18 + 10 + \frac{ 3 }{ 7 }+\frac{ 14 }{21 }\]

OpenStudy (abbie):

I did that

OpenStudy (agent0smith):

Now you just convert 3/7 to 9/21, then easily add the last two fractions \[\large 18 + 10 + \frac{ 9 }{ 21 }+\frac{ 14 }{21 }\]then simplify

OpenStudy (***[isuru]***):

OMG! srry for making u going in circles... @agent0smith method is sooo easy...

OpenStudy (abbie):

I got 28 23/21

OpenStudy (agent0smith):

haha @***[ISURU]*** yeah i often take the long method at first too... then someone points out the shortcut. 28 23/21 = 28 + 21/21 + 2/21

OpenStudy (abbie):

what do i do next?

OpenStudy (abbie):
