tolong bantuin ya teman teman

Diketahui :
A = 1 ⅓ B
B = 1 ¼ C
A + B + C = Rp 47.000

ditanyakan :
besar uang masing masing ?

penyelesaian :
B = 1 ¼ C = 5/4 C
A = 1 ⅓ B = 4/3 B = 4/3 × 5/4 C = 5/3 C

A + B + C = Rp 47.000
5/3 C + 5/4 C + C = Rp 47.000
(5/3 + 5/4 + 1) C = Rp 47.000
(20/12 + 15/12 + 12/12) C = Rp 47.000
47/12 C = Rp 47.000
C = Rp 47.000 ÷ 47/12
C = Rp 47.000 × 12/47
C = Rp 12.000

A = 5/3 C = 5/3 × Rp 12.000 = Rp 20.000
B = 5/4 C = 5/4 × Rp 12.000 = Rp 15.000
