8/25*0.25+1/4*57/25-(1-0.75)这么简便计算?
8*0.25/25+57/100-0.25=8/100+57/100-25/100=0.4
8/25*0.25+1/4*57/25-(1-0.75)这么简便计算?
1/4×0.75+0.25×3/8+25%×1/8
(-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%)
1/4/(5-0.25-12/25)算式
25%×10+1/4×11-0.25 简便
4/5÷(-1)还有 -0.25÷3/8 和 (-8/25)x1.25x(-8) 全部需4/5÷(-1)还有 -0.25÷3/8 和 (-8/25)x1.25x(-8)
4/1乘0.75-0.25乘3/8+25%乘1/8简便计算,
0.25×8分之3+8分之5×25%+4分之1(简算要过程)
0.25*8/3+8/5*25%+1/4怎么写啊
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%)
(270)*4/1+0.25*21.5+(-8又2/1)*(-25%) 简便方法计算
15-3.75×10%-5/8和9/5×25%+1/4×2.2-0.25简便运算
0.25=4分之1=25%=2/8=( )/16=3:12
0.75:8分之1= 4:0.25= 1.2:2又4分之1= 4分之3= 0.25:25= 9分之8:2=
(-370)*(-1/4)+0.25*24.5+(-5又1/2)*(-25%)
(-421)×(-1/4)-0.25×(-7 1/2)-28.5×25%
39*1/4+27*0.25+34*25%的简算
