1. A = 1 1/2 B dan B = 1 2/3 C. Berapakah perbandingan A : B : C 2. A : B = 4 : 6 dan B : C = 2 : 5. jika B = 36. berapakah A dan C..?

1. A = 3/2 B ======> A : B = 3:2 B = 5/3 C ======> B : C = 5:3 A : B : C = (3 x5) : (2 x 5) : (2 x 3) = 15:10:6 2. A:B: C = 8:12:30 A = 8/12 x 36 =..... C = 30/12 x 36=.....

1) A = 1 1/2 B --> A = 3/2 B B = 1 2/3 C --> B = 5/3 C --> C = 3/5 B A : B : C 3/2 B : B : 3/5 B --> ketiga ruas dikali 10 15 B : 10 B : 6 B --> ketiga ruas dibagi B 15 : 10 : 6
B = 5/3 C ======> B : C = 5:3
A : B : C = (3 x5) : (2 x 5) : (2 x 3) = 15:10:6
2. A:B: C = 8:12:30
A = 8/12 x 36 =.....
C = 30/12 x 36=.....
B = 1 2/3 C --> B = 5/3 C --> C = 3/5 B
A : B : C
3/2 B : B : 3/5 B --> ketiga ruas dikali 10
15 B : 10 B : 6 B --> ketiga ruas dibagi B
15 : 10 : 6
2) A : B : C
4 : 6
2 : 5
8 : 12 : 30
B = 36
A = 8/12 x 36 = 24
C = 30/12 x 36 = 90
semoga membantu ya :)
