30 % of A = 0.25 of B
3A/10 = B/4
12A = 10B
A/B = 10/12
A/B = 5/6
A : B = 5 : 6
0.25 of B = 1/5 of C
B/4 = C/5
B/C = 4/5
B : C = 4 : 5
A. B. C
5. 6
× 4. 5
20. 24. 30
so A : B : C = 20 : 24 : 30
3A/10 = B/4
12A = 10B
A/B = 10/12
A/B = 5/6
A : B = 5 : 6
0.25 of B = 1/5 of C
B/4 = C/5
B/C = 4/5
B : C = 4 : 5
A. B. C
5. 6
× 4. 5
20. 24. 30
so A : B : C = 20 : 24 : 30
