Under simplification: 20; 8 = 36; 2 = 68: 102 = 1 / 3: 4 / 5 = 7: 3 / 21: 5 = 15: 4 / 24: 0.32: 0.8=
Then 1:0.25 = 1.35:9.25=
Good passers-by, hurry

20. 8 = 5:2 36; 2 = 18:168:102 = 3:23:1:5:4 = 1 / 3 * 5 / 4 = 5 / 12 = 5:127:3:21:5 = 3 / 7 * 21 / 5 = 9 / 5 = 9:515:4:24:4 = 4 / 15 * 24 / 4 = 8 / 5 = 8:50.32:0.8 = 0.32 * 100:0.8 * 100 = 32:80 = 2:51:0.25 * 4 = 4
