化简比8分之一:50

5/6:0.18=125:27 本题已解答,如果满意 请点击右下角采纳答案

八分之一比0.65化简比 1/8:0.65 =1/8:13/20 =1/8×40:(13/20×40) =5:26

解原式 =5/8×12/7 =5/2×3/7 =15/14 =15:14

0.25 :5/8 = 1/4 x 8/5 = 2/5

0.5m:20m =0.5:20 =1:40 9千克:50克 =9000:50 =180:1 16分之5:4分之1 =(16分之5×16):(4分之1×16) =5:4 4.2:0.8 =(4.2×5):(0.8×5) =21:4 5分之3:12.2 =(5分之3×5):(12.2×5) =3:61 3.2千克:600克 =3200:600 =16:3 8...

45:80=9:16=9/16 九分之四:七分之二=4/9:2/7=14:9=14/9 1.2:3.5=12:35=12/35 八分之五:0.375=5/8:3/8=5:3=5/3

10道解方程 7(2x-1)-3(4x-1)=4(3x+2)-1; (5y+1)+ (1-y)= (9y+1)+ (1-3y); 20%+(1-20%)(320-x)=320×40% 2(x-2)+2=x+1 2(x-2)-3(4x-1)=9(1-x) 11x+64-2x=100-9x 15-(8-5x)=7x+(4-3x) 3(x-7)-2[9-4(2-x)]=22 3/2[2/3(1/4x-1)-2]-x=2 25(x/3-x/2+2/5...

0.785厘米:8分米 =7/8厘米:80厘米 =(7/8×8):(80×8) =7:640 比值=7/640

25分之8比45分之24的化简 8/25:24/45 =(8/25×225):(24/25×225) =72:120 =72÷12:(120÷12) =6:10 =3:5
