طریقه مخرج مشترک گرفتن(کلاس اول)

نویسنده :رضا سازمند
تاریخ:جمعه 23 مهر 1389-01:54 ب.ظ

طریقه مخرج مشترک گرفتن:

1- اگر مخرج ها عدد اول بودند،برای گرفتن مخرج مشترک بین آنها،

اعداد را  در هم ضرب می کنیم.


2-اگر یکی از مخرج ها عدد اول ودیگری مرکب باشد،به طوری که

بر هم بخشپذیر نباشند در این حالت هم اعداد را در هم ضرب می کنیم.


3-اگر یکی از مخرج ها مخرج مشترک بین بقیه مخرج ها باشد،

در اینصورت آن عدد را  بعنوان مخرج مشترک در نظر می گیریم.


4-اگر رابطه ای بین مخرج ها وجود نداشت برای مخرج مشترک

گرفتن بین آنها از  (ک م م )استفاده می کنیم.

I've beedn surfing online greater than three hours as of late, yet I
by no means founjd any fascinating article like
yours. It's lovely price enough for me. In my view, if all webmasters and blogbgers made just right content material as you did, the internet might be a lot more useful than ever before.

Hey there superb blog! Does running a blog similar to

hoping to start my own bpog soon.Anyway, should you have any ideas or techniques for new blog owners
please share. I understand this is off topic but I just wanted to ask.
Cheers!

سلام.
ابتدا میخوام تشكر كنم بابت اینكه این مطلب رو نوشتید
اما بهتر نبود علاوه بر توضیحات، از اعداد ریاضی هم استفاده می كردید.
قصد انتقاد كردن ندارم. شماره ٤ واقعا گنگ و مبهمه. بهتره قبل از تصمیم به آموزش دادن به دیگران، خودمون "چگونه آموزش دادن" رو تمرین كنیم
