Jumlah kelereng A terhadap kelereng B=3/4, kelereng B terhadap kelereng C=2/5. Jumlah kelereng mereka bertiga 102 butir. Berapa jumlah kelereng mereka masing-masing

A : B : C = 6 : 8 : 20 A = 6/34 x 102 = 18 B = 8/34 x 102 = 24 C = 20/34 x 102 = 60

3:4 2:5 = A:B:C fpb = 2 × 5 = 10 = 3:4:10 [yang B, atas dan bawah, cari fpbnya , lalu kali untuk c] =17y
A = 6/34 x 102 = 18
B = 8/34 x 102 = 24
C = 20/34 x 102 = 60
2:5 = A:B:C fpb = 2 × 5 = 10
= 3:4:10 [yang B, atas dan bawah, cari fpbnya , lalu kali untuk c]
=17y
102÷17= 6
= y:6
= 3×6= 18 {A}
= 4×6= 24 {B}
= 10×6= 60 {C}
