Question

把下列各连化成最简整数比:
(1)0.6:1..8:3.45 (2)4又2分之1:3.6:0.81 (3)1天:12时:80分
(4)320克:25分之3千克:0.05吨.
根据以下条件,求a:b:c
(1)a:b=4:7,b:c=7:9
(2)a:b=0.5:0.8,b:c=1.2:0.5
(3)a:b=1又5分之2:2又3分之1,b:c=0.7:0.4

Answer 1

(1) 0.6:1.8:3.45 = 12:36:69=4:12:23
(2) 4又2分之1:3.6:0.81=9/2:3.6:0.81=450:360:81=50:40:9
(3) 1天:12时:80分=24*60:12*60:80=24*6:12*6:8=18:9:1
(4) 320克:25分之3千克:0.05吨=320:120:50000=32:12:5000=8:3:1250
(1) a:b:c=4:7:9
(2) a:b:c=15:24:10
(3) a:b:c=21:35:20
