✔ 最佳答案
a:b:c =3:4:6a)
1/a: 1/b
= 1/3 : 1/4
= 12/3 : 12/4
= 4 : 3
b)
1/a:1/b:1/c
= 1/3 : 1/4 : 1/6
= 12/3 : 12/4 : 12/6
= 4 : 3 : 2

(a)1/a:1/b
=1/3:1/4
=1/3*12:1/4*12
=4:3
*12=3,4 LCM
(b)1/a:1/b:1/c
=1/3:1/4:1/6
=1/3*12: 1/4*12: 1/6*12
=4:3:2
*12=3,4,6 LCM
=1/3:1/4
=1/3*12:1/4*12
=4:3
*12=3,4 LCM
(b)1/a:1/b:1/c
=1/3:1/4:1/6
=1/3*12: 1/4*12: 1/6*12
=4:3:2
*12=3,4,6 LCM
