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...

解:原式=[(3分之11-4分之11)÷6分之11+1.15]×11分之5 =[11×(3分之1-4分之1)×11分之6+1.15]×11分之5 =(11×12分之1×11分之6+1.15)×11分之5 =(2分之1+1.15)×11分之5 =1.65×11分之5 =20分之33×11分之5 =4分之3 望采纳,谢谢!

=-1^2005+(-24)x(1/8+2又2/3-2.75) =-1-24x(1/8+8/3-11/4) =-1-24x(3/24+64/24-66/24) =-1-24x1/24 =-1-1=-2

【二又五分之四+(三又三分之二减2.75)除一又六分之五】除三又五分之一 =[2.8+(11/3-11/4)x6/11]x5/16 =(2.8+11/3x6/11-11/4x6/11)x5/16 =(2.8+2-1.5)x5/16 =3.3x5/16 =33/10x5/16 =33/32 请好评 如果你认可我的回答,敬请及时采纳, ~如果你认可...

7.01×9/8+1.99×2.75+2又3/8 =7.01×9/8+1.99×22/8+19/8 =7×9/8+0.01×9/8+2×22/8-0.01×11/8+19/8 =(7×9+2×22+19)/8+0.01×1/8×(9-11) =126/8+0.01×1/8×(-2) =15.75-0.01×0.25 =15.75-0.0025 =15.7475

(1)2又四分之三-(-8又二分之一)+(-2又四分之一)+0.25-1.5-2.75 =2又3/4+8又1/2-2又1/4+1/4-1又1/2-2又3/4 =2又3/4-2又3/4 +8又1/2-1又1/2-2又1/4+1/4 =(2又3/4-2又3/4) +(8又1/2-1又1/2)+(-2又1/4+1/4) =0+7-2 =7 2. (-1.7)+|-4.3|+|-1....

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
