(x+0.6)÷1/2=15/4(解比例)

(x+0.6)÷1/2=15/4 (x+0.6)*2=15/4 8X+4.8=15 8X=10.2 X=1.275

X÷(X+3)=0.6÷1.2 解0.6(x+3)=1.2x 0.6x+1.8=1.2x 0.6x=1.8 x=3

X/2=0.15/0.6 X=2×0.15÷0.6 X=0.3÷0.6 X=0.5

4分之3(X+0.6)=2.1 解:x+0.6=2.1÷3/4 x+0.6=2.8 x=2.8-0.6 x=2.2

[0一(一3)]x(一6)一14÷[(一3)十(一2)÷4] =(0+3)×(-6)-14÷[-3+(-0.5)] =3×(-6)-14÷(-3.5) =--18-(-4) =-18+4 =-14

4.2/(x-0.6)=1.4 1.4(x-0.6)=4.2 x-0.6=3 x=3.6 1.2x-(0.6+3.4)=3.2 1.2x-4=3.2 1.2x=7.2 x=6 60%x+14=32.6 0.6x+14=32.6 0.6x=18.6 x=31

=1.08÷(0.9*0.6) =1.08÷0.9÷0.6 =1.2÷0.6 =2

(x+1.2)/0.5=6 x+1.2=0.5*6 x+1.2=3 x=3-1.2 x=1.8

(1)X:4.8=4:32, 32x=4.8×4, 32x=19.2, 32x÷32=19.2÷32, x=0.6;(2)1.60.9=x4, 1.6x=0.9×4, 1.6x=3.6,1.6x÷1.6=3.6÷1.6, x=2.15;(3)23:X=910:35, 910x=23×35, 910x=25, 910x÷910=25÷910, x=49;(4)2.5:4=1.25:X, 2.5...

1.4+0.6=2 最后小括号里面0.24*(7.08-2.08),运用分配律,0.24*5=1.2,0.96/1.2=0.8,2/0.8=2.5
