复习分数简便计算一、指导方法分数的简便运算与整数、小数的方法是一样的,整数的简便运算定律和性质在分数和小数中同样适用。在分数的相关计算中,要想到凑整。二、基本运算定律 1、 加法交换律:a+b=b+a 加法结合律:(a+b)+c=a+(b+c) 2、 乘法交换律:a×b=b×a 乘法结合律:(a×b)c=a(b×c) 乘法分配律:(a+b)×c=a×c+b×c 3、添去括号法则:括号前是加号(乘号),添去括号不变号括号前是减号(除号),添去括号要变号三、专项练习 1、利用加法运算定律简算(适用连加算式)(1)1/4+3/5+3/4 (2)2/3+2/5+1/3+3/5 2、利用乘法交换律和结合律简算(适用连乘算式)(1)1/3×3/7×7/3 (2)1/4×3/25×4 (3)3/26×5/7×39 3、利用乘法分配律简算(适用有乘有加的算式)(1)7/11×2/7+7/11+5/7 (2)3/8×4/9+5/9×3/8 (3)25×(3/5+1/25) (4)3/7×6+3/7 (5)(1/3+5/8)×24
