15÷(x一6)=3

15÷(x一6)=3 解:原方程即, 15÷(x一6)=3 x-6=15÷3 x-6=5 x=5+6 x=11

(-15)÷(1/3-3/2-3)×6 解:原式=(-15)÷(-25/6)×6=(-15)÷(-25错)=-3/5错 第一错为直接将6与分-25/6相约 第二错为负负就为正,但结果仍不负 正确为: (-15)÷(1/3-3/2-3)×6 =-15*(-6/25)*6 =15*36/25 =108/5

=3.15×(6.2÷9.3) =3.15×2/3 =2.1

(15.3+3.8x6.5)÷1.6 =16÷1.6+(1.9x2x6.5-0.7)÷1.6 =10+(1.9x13-0.7)÷1.6 =10+(2x13-0.1x13-0.7)÷1.6 =10+(26-2)÷4÷0.4 =10+6÷0.4 =10+15 =25

解: 4/15÷(1又4/9-2/3×5/6)+5/6 =4/15÷(13/9-5/9)+5/6 =4/15*(9/8)+5/6 =3/10+5/6 =9/30+25/30 =34/30 =17/15

(3x一6)÷6=15 3×—6=15×6 3×—6=90 3×=96 ×=32

(6/5)÷[(2/3)×15] =(6/5)÷10 =(6/5)X(1/10) =3/25。

15.6÷4-3.5x=1.1 3.5x=3.9-1.1 x=2.8÷3.5 x=0.8

3(X+1)÷(2X–4)= 6 3(x+1)=6(2x+4) 3x+3=12x+24 3x-12x=24-3 -9x=21 x=21/-9=-7/3

先计算15.6/1.5,得出为 10.4,然后再计算10.5-10.4=0.1,最后算3.2*0.1=0.32 答案为0.32
