(2.63+3/8)*(25+2/5)*(2.37-3/8)*(25+2/5)
(2.63+3/8)*(25+2/5)*(2.37-3/8)*(25+2/5)
(2.63+3/8)*(25+2/5)*(2.37-3/8)*(25+2/5)
中间是加号吧
(2.63+3/8)*(25+2/5)+(2.37-3/8)*(25+2/5)
=(2.63+2.37+3/8-3/8)(25+2/5)
=5x(25+2/5)
=5x25+5x2/5
=125+2
=127

一道计算题,要求过程和答案4.73-[8/3-(9/5+2.63)]-1/3
4.73-【2又3分之2-(1又5分之4+2.63)】-3分之1
4.73-[2 +2/3-(1+4/5+2.63)]-1/3数学题,要有过程
4.73-【2又2/3-(1又4/5+2.63)】-1/3
小学六年级列式计算两道求助!(1) 2.63与2.37的和除以0.25,所得的商比25少多少?(2) 1/5与6的倒数之和,除以5/6与3/8的差,商是多少?

3/8+(2/5-6/25)=?
(1)1375-375÷15×18= (2)40.5÷0.81-16×0.24= (3)2/5×25×5/6×4= (4)12×(1/4+1/6+1/3)=(5)(3/10×5/6+3/10)÷9/4= 能简便运算就简便运算列式计算(1)2.63与2.37的和除以0.25,所得的商比25少多少?(2)1/5
(-3/2)-13/4+(-13/3)-8/3=,49.7-[-23又3/4+(18.7-25.25]=,|12.7-(-8.9)|=,4.73-[2又2/3-(1又4/5+2.65]-1/2最后一个分数是1/3,2.65改为2.63
10(1/5x-2)=25(8/5x+3/25)-2
10(1/5X--2)=25(8/5X+3/25)-2
4.73-[2又3分之2-(-2.63)】-3分之1快,我明天要交的
计算:4.73-【2又3分2-(-2.63)】-1/3
