3-8/9×6/5÷32/3 (1-1/4×8/9)×9/7 (5/6+1/3)÷(3/4-2/3) 3/4÷(1/2-1/3)÷3/2
问题描述:
3-8/9×6/5÷32/3 (1-1/4×8/9)×9/7 (5/6+1/3)÷(3/4-2/3) 3/4÷(1/2-1/3)÷3/2
(简便计算)
答
3-8/9×6/5÷32/3 (1-1/4×8/9)×9/7 (5/6+1/3)÷(3/4-2/3)
=3-1/10 =(1-2/9)X9/7 =7/6÷1/12
=2又9/10 =1 =14
3/4÷(1/2-1/3)÷3/2
=3/4÷1/6÷3/2
=38/15×(3/8+14/15÷7/10)12÷【(7/9-2/3)×9/10】3/10×20/3-5/8÷5/25/8-6/25×5/2+1/4 (这几条再帮忙一下,会加分的8/15×(3/8+14/15÷7/10)12÷【(7/9-2/3)×9/10】 3/10×20/3-5/8÷5/2=8/15X(3/8+4/3) =12÷1/10=2-1/4=41/45 =120 =1又3/45/8-6/25×5/2+1/4 =5/8-3/5+1/4=11/40
