34-37分之34的差÷17×12分之五简便计算
解：采用分配律
原式=（34-34/37）÷17x5/12
=（34x1/17-34/37x1/17）x5/12
=（2-2/37）x5/12
=72/37x5/12
=30/37
34-37分之34的差÷17×12分之五
=34x(1-1/37) ÷17×12分之五
=34 ÷17x(1-1/37)×12分之五
=2x 37分之36 ×12分之五
=30/37
解: (34-34/37)÷17×5/12
= (34-34/37)×1/17×5/12
=34×1/17×5/12+34/37×1/17×5/12
=2×5/12+2/37×5/12
=5/6+5/222
=(185+5)/222
=190/222
=95/111
