0.78+5.436+1 4.07×0.86+9.12.5
六年級上冊數(shù)學(xué)簡便例子演示17×62+62×63
解題思路:四則運(yùn)算規(guī)則(按順序計(jì)算,先算乘除后算加減,有括號先算括號,有乘方先算乘方)即脫式運(yùn)算(遞等式計(jì)算)需在該原則前提下進(jìn)行
解題過程:
17×62+62×63
=（17+63）×62
=80×62
=4960
擴(kuò)展資料【豎式計(jì)算-計(jì)算結(jié)果】:先將兩乘數(shù)末位對齊,然后分別使用第二個(gè)乘數(shù),由末位起對每一位數(shù)依次乘上一個(gè)乘數(shù),最后將所計(jì)算結(jié)果累加即為乘積,如果乘數(shù)為小數(shù)可先將其擴(kuò)大相應(yīng)的倍數(shù),最后乘積在縮小相應(yīng)的倍數(shù)；
解題過程:
步驟一:2×80=160
步驟二:6×80=4800
根據(jù)以上計(jì)算結(jié)果相加為4960
存疑請追問,滿意請采納
1.甲乙共有前2000元，甲把它的一半給乙，然后乙把它的1/3再給甲，之后甲把它的1/4給乙，這時(shí)乙比甲多650元，問最初兩人各有多少元？
2.歡歡和欣欣都愛好集郵，他們各有郵票若干長，歡歡拿出1/6給欣欣后，欣欣拿出1/5給歡歡，這時(shí)她們各有240張。原來她們各有郵票多少張？
3.我校種樹，楊樹占總數(shù)的5/9，其余的種柳樹。后來又買來20棵楊樹。這是楊柳樹的比是15：11。學(xué)校共種樹多少棵？
4.公園買來三種樹苗。其中松樹占總數(shù)的30%，楊樹與柳樹的比是2：5，已知柳樹比松樹多40棵，一共買來多少樹苗？
5.甲乙丙三個(gè)村合修一條長1000千米的水渠，修成后受益面積。甲與丙村的比是3：1，乙村的3/4等于甲村的2/3。各村按受益面積分配。各應(yīng)修多少千米？
6.我校有學(xué)生840人。其中4、5、6年級占總數(shù)的2/3.已知四與六年級人數(shù)的比是3：5。五年級的3/4等于四年級的2/3。四年級有多少人？
7.一套桌椅共300元,椅子的價(jià)錢比桌子少十一分之七,桌椅各多少元?
8.一件工作，計(jì)劃10天完成，實(shí)際8天完成，工作時(shí)間縮短了幾分之幾？工作效率提高了幾分之幾？
9.果園里西紅柿獲得豐收，摘下全部的3/8時(shí)，裝滿了若干筐還多24千克，摘完其余部分時(shí)，又剛好裝滿6筐。
以上就是六年級數(shù)學(xué)上冊口算的全部內(nèi)容，口算：1+20%=120 脫式： 3.14*4/2 =12.56/2 =6.28 簡算： 20%*2+20%*5 =20%*(2+5)=20%*7 =140 應(yīng)用：一張圓桌子半徑是2米周長和面積分別是多少？。
