Thank you.

OpenStudy (k_lynn):

You need to reduce that fraction. Can you do that for me?

OpenStudy (anonymous):

how

OpenStudy (k_lynn):

what number goes into both 18 and 24?

OpenStudy (anonymous):

one sec please

OpenStudy (k_lynn):

sure.

OpenStudy (anonymous):

72 18 goes into 72 4 times and 24 goes into 72 3 times

OpenStudy (k_lynn):

actually, what I'm saying is like, you can multiply 3x6 to get 18. Can you multiply 3 or 6 by any other number to get 24?

OpenStudy (anonymous):

6x3=18 6x4=24

OpenStudy (k_lynn):

right. So 18 and 24 have a common multiple of 6. You just need to do this now. |dw:1421414343485:dw|
