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

3.5÷0.8×2.7+7.3-1＝（0.7×5）÷0.8×（0.3×9）+6.3=0.7×9×（5×0.30.8）+6.3=6.3（15/8+1）=18又9/80

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

6.4乘0.25加3.6除以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)]

4936*(0.75*42.7-0.573*25+57.3)/3=4936*(0.75*42.7-25*0.573+100*0.573)/3=4936*[0.75*42.7+(100-25)*0.57
