数学分式的基本性质(约分)填空:三分之二 = 六分之几 = 几分之六 = 几分之1002y分之2x = 6xy分之几 = 几分之6xy = 几分之100x^2y^2x+2分之x+1 = 几分之2x+2 = 3x+6分之几 = 几分之x^2+x = 2x^3+4x^2分之几
数学分式的基本性质(约分)
填空:
三分之二 = 六分之几 = 几分之六  = 几分之100
2y分之2x = 6xy分之几 = 几分之6xy = 几分之100x^2y^2
x+2分之x+1 = 几分之2x+2 = 3x+6分之几 = 几分之x^2+x = 2x^3+4x^2分之几
约分:
   1.16a^2分之4a^2 = _____________

   2.负 27x^2y^2分之18xy = _______________
   3.16n^3m^2分之负24n^2m^3 = ________________
   4.20(x+y)(x+2y)分之12(x+y)^2 = ____________________

数学分式的基本性质(约分)填空:三分之二 = 六分之几 = 几分之六 = 几分之1002y分之2x = 6xy分之几 = 几分之6xy = 几分之100x^2y^2x+2分之x+1 = 几分之2x+2 = 3x+6分之几 = 几分之x^2+x = 2x^3+4x^2分之几

三分之二 = 六分之4 = 9分之六 = 150分之100
2y分之2x = 6xy分之6(x的平方) = 6(y的平方)分之6xy = 几分之100x^2y^2(最后一个不知什么意思)
