22又二分之一乘6%加2.75除与一又三分之2加1.2简便计算

简便计算 22又1/2×6%+2.75÷1又2/3+1.2 =2.25×0.6+2.75×3/5+0.6×2 =(2.25+2.75+2)×0.6 =7×0.6 =4.2

二又四分之三乘3.75减二又四分之三加七又四分之一乘2.75 =2.75×(3.75-1+7.25) =2.75×10 =27.5 乘法分配律 供参考,有疑问请追问

您好: (-二又三分之一)加一又二分之一加(-5.25)+(-一又三分之二)加(-八又二分之一)-2.75 =(1.5-8.5)-(5.25+2.75)-(2又1/3+1又2/3) =-7-8-4 =-19 3又二分之一-(-2又四分之一)+(-三分之一)-0.25+(+六分之一) =(3.5+2.25-0.25)-(1/3-1/6...

2.75+(2又3/4+(1又1/8)+(-14又5/7)+(-5.125) =(2.75+2又3/4)+(1又1/8-5.125))+(-14又5/7) =4.5-4-14又5/7 =1/2-14又5/7 =-14又3/7

简便计算 22又1/2×6%+2.75÷1又2/3+1.2 =2.25×0.6+2.75×3/5+0.6×2 =(2.25+2.75+2)×0.6 =7×0.6 =4.2

--> -1/2+-1/3+2.75-(6+1/2) ans = -4.5833

题目不完整 ,无法作答

-0.5-(-2又1/4)+2.75-7又1/2 =-0.5+2.25+2.75-7.5 =-(0.5+7.5)+(2.25+2.75) =-8+5 =-3

等于-2。

付五又二分之1+负三又四分之3+正2.75加负二点五 =-5.5-3.75+2.75-2.5 =(-5.5-2.5)-(3.75-2.75) =-8-1 =-9
