求比值猛敬埋
80:24 0.5:0.2 0.15:21 36:18 13:91 3:12 1.01:101 21:24 36:72 20:40 89.5:2 10.5:21 3.14:28.26 41.23:4123 15:0.12 10:120 123:3 65:13 3:1 42:54 、

化简比枝蚂
24:27 12:18 45:54 31:61 21:28 20:30 5:75 12:2 30:21 35:70 2:300

方程稿消
X-2/7X=3/4
70%X + 20%X = 3.6
25% + 10X =4/5
X - 15%X = 68
X+3/8 X=121
5X-3×5/21 =5/11
6X+5 =13.4
X÷(6/35) =(26/45) ×(13/25)
2(x-0.6)=4
(0.5+x)+x=9.8÷2
2(X+X+0.5)=9.8
25000+x=6x
