在1到200的所有自然數中,既是3的倍數,又是4的倍數,又是5的倍數的數一共有多少個?

在1到200的所有自然數中,既是3的倍數,又是4的倍數,又是5的倍數的數一共有多少個?


3,4,5的最小公倍數為3×4×5=60
既是3的倍數,又是4的倍數,又是5的倍數的數,一定是它們三個的公倍數
在1到200的所有自然數中有60120180,一共3個.
很高興為您解答,如果本題有什麼不明白可以追問,



在1至100的自然數中,是3的倍數和是5的倍數的數一共有多少個?


是3的倍數的數有3 6 9 12 15.99,數量為33個
是5的倍數的數有5 10 15 20.100,數量為20個
是3的倍數同時是5的倍數的數有15 30 45 60 75 90,數量為6個
那麼是3的倍數和是5的倍數的數一共有33+20-6=47個



一個自然數與它的倒數之和是5.2,這個自然數是______.


把5.2化成分數是515515=5+15,5×15=1;所以這個自然數是5.故答案為:5.

The only thing more lamentable than repeating history because we failed to learn from our mistakes would be repeating history because others failed to learn from them.這兩個because連用我有點蒙.


主語是the only thing動詞時would be
所以兩個because處於不同的結構中
翻譯過來是:與別人因為不能吸取他們以往的教訓而重複歷史的錯誤相比,更令人惋惜的唯一一件事就是我們自己因為沒有從我們過去的錯誤中吸取教訓而重複了以前的錯誤.

A method for refractometer measuring,in which a beam of rays emitted from a light source is transmitted to the interface between the optical window of a refractometer and the liquid to be measured,whereby part of the beam of rays is reflected back from the liquid and part is absorbed into the liquid and an image is produced in which the position of the boundary between a light and dark area depends on the critical angle of total reflection,the critical angle being a function of concentration of liquid,and in which the boundary between the light and dark area of the image is determined by light detectors arranged in aline.Forgood resolution,to the measuring data obtained from the light detectors is applied a mathematical model corresponding with the information provided by the measuring data and the position of the boundary is determined by means of this model.


refractometer量測的一種方法,其中一束光線從光源發出傳送給光學視窗之間的介面和液體的refractometer,藉此來衡量的一部分被反射回束光線從液體及部分是被吸收到液體和一幅影像中產生的位置之間的邊界地區一個光明與黑暗取決於極限角的角度反思、臨界總額作為一種功能
濃度的液體,在光明與黑暗之間的邊界區域的影像是由光探測器排列在一條線.因為分辯率好,對量測數據中獲得光探測器是應用數學模型與相應所提供的資訊的量測數據與定位邊界的管道確定該模型.

,1,跟老外交流,遇到他說的哪個單詞不懂,我怎麼說才行?what 's mean by xxxx?
1,開場的時候說,我的英文不是很好,請別介意,怎麼說?,
3,你認為這個地方怎麼樣


1,你最好重複一下你不懂的那個單詞給他聽.xxx?What does it mean?
what's the mean by xxx.這種表達是不對的.因為what‘s中的is和mean都是動詞,不行.
非要這樣說的話就改為What's the meaning of xxx.
2,既然是開場的時候說,我猜你是主要想表達你的口語不是很好可以這樣說:My English is a little broken,hope you won't mind.
3,How's this place?用how is提問認為怎麼樣
