1/4×0.75+0.25×3/8+25%×1/81/4×0.75+0.25×3/8+25%×1/81/4×0.75+0.25×3/8+25%×1/8原式=1/4×0.75+(0.25×3/8+0.2
1/4×0.75+0.25×3/8+25%×1/8
1/4×0.75+0.25×3/8+25%×1/8
1/4×0.75+0.25×3/8+25%×1/8
原式=1/4×0.75+(0.25×3/8+0.25×1/8)
=1/4×0.75+0.25×(3/8+1/8)
=1/4×3/4+1/4×1/2
=1/4×(3/4+2/4)
=1/4×5/4=5/16
1/4×0.75+0.25×3/8+25%×1/8
4/1乘0.75-0.25乘3/8+25%乘1/8简便计算,
|-0.75|+(+3又1/4)-(-0.125)-|-0.25|+(+5/8)
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=
8/25*0.25+1/4*57/25-(1-0.75)这么简便计算?

1.计算 1又3/4-0.25 .0.125*2/3 .0.063*1/9.1又4/8-0.75.
[(0.75+1分之5)除以0.25-3又5分之4]乘1999又25分之24
0.25+(-3又2分之1)+0.75+(13又4分之3)-(-8又7分之3)
/-0.75/+(+3又4分之1)-(-1.125)-/-0.25/+1又8分之5
简便计算:8×[0.75-0.25×(4-2)]
