一个数除以0.5等于这个数乘2一个数除以0.25等于这个数乘4一个数除以0.2等于这个数乘5
6.25/0.25*6=(6/0.25+0.25/0.25)*6=(24+1)*6=25*6=150
18.7*0.25-18.7/4=0.25*4-18.7/18.7=0
0.81/0.27=30.75/0.25=30.84/0.24=7/2原式=3*3*7/2=63/2
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
5.6乘1.25=7x0.8x1.25=7x1=711.1除以0.25.=11.1x4÷(0.25x4)=44.4÷1=44.4457除以25除以4=457÷（25x4）=457÷100=4.5721
0.25*1.25/(1/32)=0.25*1.25*32=0.25*4*1.25*8=1*10=10
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
把小数写成分数,直接约分
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
18.76乘9.9加1.876=18.76*9.9+18.76*0.1=18.76*(9.9+0.1)=18.76*10=187.615.7除以（15.7除以0.4）=15.7除以（15.7/0.4）
(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
(6.9*0.25*1.75)=6.9*(1/4)*(7/4）(6.9*0.25*1.75)/[2.3*(1/8）*(1/4)]＝[6.9*(1/4)*(7/4)]/[2.3*(1/8）*(1/4)]
0.525÷0.25÷4×100=0.525÷(0.25×4)×100=0.525÷1×100=52.5
(0.75除以0.2)除以0.25乘25%=0.75÷0.2×(25%÷0.25)=3.75×1=3.75
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
