望采纳谢谢.(1)2.5*32*0.125 =(2.5*4)*(8*0.125) =10*1 =10 (2)3.5-7+6.5 =3.5+6.5-7 =3 (3)1.2*2.5+0.8*2.5 =2.5(1.2+0.8) =25 (4)8.9*1.25-0.9*1.25 =1.25(8.9-0.9) =10 (5)12.5*7.4*0.8 =12.5*0.8*7.4 =74 (6)6.5*9.5+6.5*0.5 =6.5*(9.5+0.5) =6.5*10

解: (1)(3/4÷3/5+1/4)*6/13 =(3/4**5/3+1/4)*6/13 =6/4*6/13 =9/13 (2)35÷(7/8*(1-2/7)) =35÷(7/8*5/7) =35*8/5 =56 (3)(6-3又3/5*2/3)÷3又3/5 =6*5/18-2/3 =5/3-2/3 =1 (4)6.15÷2又1/2-1/3*(1/20+4.36) =6.15*2/5-1/60-4.36÷3 =2.46-1/60-436/300 =2.97 (5)(1又1/2-0.375)÷(1/25*(2/5+2.1)) =(1.5-0.375) ÷(1/25*25/10) =1.125*10 好了,看得懂吗
