Jawab:
Perbandingan
Penjelasan dengan langkah-langkah:
2/3 A = 3/4 B --> 8A = 9 B
A : B = 9 : 8
.
2/3 B = 3/5 C --> 10 B = 9 C
B : C = 9 : 10
maka
A = 9 x 9 = 81
B = 9 x 8 = 72
C = 8 x 10 = 80
yang terkecil B = 72
Ikutan ...
3 bilangan : A, B, C
2/3 A = 3/4 B
A/B = 3/4 × 3/2 = 9/8
2/3 B = 3/5 C
B/C = 3/5 × 3/2 = 9/10
A : B : C = (9 × 9) : (8 × 9) : (8 × 10)
A : B : C = 81 : 72 : 80
Paling kecil → B
