8分之7乘4分之1加0.25乘0.125=7/8x1/4+1/4x1/8=1/4x(7/8+1/8)=1/4x1=1/415分之2乘【12.6减(5分之33加0.125除以12.5%)】=2/15x(
18.7*0.25-18.7/4=0.25*4-18.7/18.7=0
X除以0.25乘4X=4分之一x乘4X=1
8.26除以4减4.26乘0.25=8.26*0.25-4.26*0.25=0.25*（8.26-4.26）=0.25*4=1
(0.5x2)+(0.25x4)+(0.125x8)=1+1+1=3
5.23乘4加4.77除以0.25=5.23×4+4.77×4=（5.23+4.77）×4=10×4=40
3.64÷4+4.36×0.25=3.64×1/4+4.36×0.25=3.64×0.25+4.36×0.25=0.25×（3.64+4.36）=0.25×8=2
原式=21/26×39/35×10/9=21/26×39/63=1/2原式=1/8×11/4+1/4×17/4+1/8=1/8×（11/4+1）+17/16=15/32+34/32=49/32
3除以1乘2+3除以2乘3+3除以3乘4+3除以4乘5+···+3除以99乘100=3×（1-1/2+1/2-1/3+1/3-1/4+1/4-1/5+……+1/99-1/100）=3×（1-1/100
4.7乘4分之1加0.25乘4.3减1除以4=4.7*1/4+0.25*4.3-1/4=1/4(4.7+4.3-1)=1/4*8=2
5.75/0.25+4.24×4=5.75×4+4.24×4=(5.75+4.24)×4=9.99×4=(10-0.01)×4=40-0.04=39.96再问：5.75乘4是设么意思再答：5.75/0
(1.6乘4)乘0.25加3.6除4=1.6乘4乘0.25加0.9=1.6乘1加0.9=1.6+0.9=2.5
4.9*4+5.1除以0.25=4.9*4+5.1*4=（4.9+5.1）*4=10*4=40

0.525÷0.25÷4×100=0.525÷(0.25×4)×100=0.525÷1×100=52.5
原式=1/[2×(2+2)]+1/[(2+2)×(2+4)]+……+1/[(2014-2)×2014]=（1/2-1/2014）×1/2……（裂项相消公式的运用）=1006/4028
4分之1或7744分之84
5.23÷4/3+5.25x0.25=(5.25-0.02)x3/4+5.25x1/4=5.25x3/4+5.25x1/4-0.02x3/4=5.25(3/4+1/4)-0.015=5.235满意请点
7.05÷4-3.05×0.25=7.05×1/4-3.05×1/4=（7.05-3.05）×1/4=4×1/4=1
1乘以0.4除以1乘0.4得多少?1乘0.4=0.4除1=0.4乘0.4=0.1625乘4除以0.25乘4得多少?25乘以4=100除以0.25=400乘4=1600
