分数
分数的加、减法则：同分母的分数相加减，只把分子相
加减，分母不变。
异分母的分数相加减，先通分，然后再加减。
分数的乘法则：用分子的积做分子，用分母的积做分母。
分数的除法则：除以一个数等于乘以这个数的倒数。
加法交换律a＋b＝b＋a
加法结合律a＋b＋c＝(a＋b)＋c＝a＋(b＋c)＝(a＋c)+b
乘法交换律ab＝ba 乘法结合律abc＝(ab)c＝a(bc)＝(ac)b
乘法分配律a(b＋c)＝ab＋ac
减法的运算性质a－b－c＝a－(b＋c)
除法的运算性质a÷b÷c＝a÷(b×c)
商不变的性质
a÷b＝(a×x)÷(b×x)＝(a÷x)÷(b÷x)(x≠0)
分数的基本性质
比的基本性质a:b＝(a×x):(b×x)＝(a÷x):(b÷x)(x≠0)
