(-270)*0.25+0.25*21.5+(-8.5)*(-0.25)
(-270)*0.25+0.25*21.5+(-8.5)*(-0.25)
(-270)*0.25+0.25*21.5+(-8.5)*(-0.25)
-60
(-270)*0.25+0.25*21.5+(-8.5)*(-0.25)
(-270)*0.25+0.25*21.5+(-8.5)*(-0.25)=?
0.25:
(-270)*0.25+0.25*21.5+8.5*(-25%)=多少
(-270)×0.25+0.25×21.5+(-8.5)×(-25%)等于几-147×(0.1250+253×0.125+72×(-0.25)
(-270)*1/4+0.25*21.5+(-8 1/2)*(-25%)
(-270)*1/4+0.25*21.5+(-8 1/2)*(-25%)(-270)*1/4+0.25*21.5+(-8 1/2)*(-25%)
0.25 0.25 0.25 0.25等于0.125
0.25×8.19-0.25×4.19
(49-0.25)/0.25+(46-0.25)/0.25+(43-0.25)/0.25+.+(1-0.25)/0.25等于多少?
(-270)×0.25+0.25×21.5+(-8.5)×(-25%)等于几第一个是简便运算还有一个不是简便运算的:-147×(0.125)+253×0.125+72×(-0.25)
初中有理数乘法(-270)*1/4+0.25*21.5+(-81/2)*(-25%)要简便方法。算式应该是(-270)*1/4+0.25*21.5+(-8又1/2)*(-25%)
41*0.25-0.25+0.25*60 简便计算
0.4:0.25
0.25x
0.25是什么意思
(270)*4/1+0.25*21.5+(-8又2/1)*(-25%) 简便方法计算
(-270)乘四分之一+0.25乘21.5+(-8又2分之1)乘(-25%)用简便计算
