Uang A = 2 per 3 uang B dan uang B = 2 per 5 uang C jika jumlah uang mereka Rp75.000 Tentukan besar uang masing-masing! tolong beserta cara ya

a = 2/3 b
b = 2/5 c
a+b+c = 75.000

Dit : a? b? c?

Jawab :
a+b+c = 75.000
2/3 b +b+c = 75.000
5/3b + c = 75.000
5/3(2/5 c) + c = 75.000
2/3c + c = 75.000
5/3 c = 75.000
c = 75.000 × 3/5
c = 45.000

b = 2/5 c
b = 2/5 (45.000)
b = 18.000

a = 2/3 b
a = 2/3 (18.000)
a = 12.000

semoga membantu :) maaf kalau ada yg salah
