1. 1200的三分之一是多少
1200的三分之一是400。
計算過程如下:
1200x1/3
=1200÷3
=400
所以1200的三分之一是400。
分數計算的性質:
分數乘整數,分母不變,分子乘整數,最後能約分的要約分。分數乘分數,用分子乘分子,用分母乘分母,最後逗好能約分的要約分。
分數除以整數,分母不變,如果帆賣分子是整數的倍數,則用分子除以整數,最後能約分的要約分。
分數除以整數,分母不變,如果分子不是整數的倍數,則用這個分數乘這個整數的倒數,最後能約分的要約山轎鉛分。
2. 1200除以0等於多少
0不能作除塌穗戚數。
當0是除數的時候,也就是把被除數平均分團陵成0份,但實際上沒族簡有這樣的情況發生,就算被除數不分份,至少也是一份,所以,讓0作除數沒有意義。
另外,反過來看,如果0是除數,那麼它與商相乘,就是被除數,不論商是什麼,被除數總得0,這樣被除數不能確定,所以,0不能作除數。

小數乘法豎式注氏陵意事項
1、列豎式時,是因數的尾數對齊。
2、列豎式時,為了計算方便數位多的因數一般放在上面。
3、如果有整十整百整千類的因數時,兩個因數的從右數第一位非零數對齊,然後再在得數里填上相應個數的0。
4、如果得數的末尾有0,先點完小數點再去0。
5、如果小數的位數不夠,需要在前面補0佔位。
小數乘法的意義
小數乘整數的意義與整數乘法的意義相同,就是求幾個相同加數的和的簡便運算。一個數乘小數的意義是求這個數的十分之幾、百分之幾、千分之幾……
小數除法的意陸核肢義:小數除法的意義與整數除法的意義相同,是已知兩個因數的積與其中的一個因數,求另一個早世因數的運算。
5. 111除以零點三的豎式還有6.92乘0.84的是
111÷0.3
=1110÷3
=370
6.92賀局×0.84=5.8128
