Answer 1

解比例：
3/5: x = 1/3: 2
x = 3.6
3:8 = 15:x
x = 40
x:9 = 4:7
x = 12
1/4:1/8 = x:1/10
x = 1/5
1.25:0.25 = x:1.6
x = 8
3/4:x = 3:12
x = 3
5:8 = 40:x
x = 64
x:3/4 = 1/5:2/5
x = 3/8
140:2 = x:5
x = 350
6.5:x = 3.25:4
x = 8
X:20 = 0.4:6
6x = 20 * 0.4
x = 4/3
x:10 = 1.1/(0.4:x) = 1.2:2
12/3 = 2.4
x = 2.4
3/4 = 3:2.4
x = 3
14:x = 0.8:4
x = 5
1.25:0.25 = x:1.6
2_8 = 36549x
x = 36549/28
x:3x = 6:24
x = 3
4.563 = 25x
x = 4.563/25
2.2 = 45:x = 18:26
x = 2.2 * 26 / 18
1:x = 1:8
x = 8
2.8:4.2 = x:9.6
x = 2.8 * 9.6 / 4.2
x:24 = 3.143
x = 3.143 * 24
8:x = 4:5
x = 8 * 5 / 4
16 = x:12
x = 16 * 12
11 = x:10.6
x = 11 * 10.6
0.6:4 = 2.4:x
x = 4 * 2.4 / 0.6
6:x = 5:3
x = 6 * 3 / 5
12 = x:11
x = 12 * 11
4:2 = x:5
x = 4 * 5 / 2
11 = x:10.6
x = 11 * 10.6
1.3:x = 5.2:20
x = 1.3 * 20 / 5.2
x:3.6 = 6:18
x = 3.6 * 6 / 18
x3:20 = 9:x
x = 9 * 20 / 3
0.2 = x:8
x = 0.2 * 8
x8 = 64
x = 64 / 8
