Uang Andi : Uang Toni = 5 : 7
Uang Toni : Uang Ridwan = 5 : 4
Uang Andi : Uang Toni : Uang Ridwan = 25(5x5) : 35(5x7) : 28(4x7)
25 + 35 + 28 = 88
Rp440000 ÷ 88 = Rp5000

Uang Andi = 25 x Rp5000 = Rp125000
Uang Toni = 35 x Rp5000 = Rp175000
Uang Ridwan = 28 x Rp5000 = Rp140000

Misalkan :

Uang Adi = A
Uang Toni = T
Uang Ridwan = R

maka :

A : T =..... 5 : 7
......T : R =..... 5 : 4

A : T : R = (5×5) : (7×5) : (7×4)
A : T : R = 25 : 35 : 28

A + T + R = Rp 440.000,00

A = 25/(25+35+28) × 440.000
A = 25/88 × 440.000
A = Rp 125.000,00

T = 35/(25+35+28) × 440.000
T = 35/88 × 440.000
T = Rp 175.000,00

R = 28/(25+35+28) × 440.000
R = 28/88 × 440.000
R = Rp 140.000,00


Jadi uang Adi , uang Toni dan uang Ridwan masing-masing adalah Rp 125.000,00 , Rp 175.000,00 dan Rp 140.000,00
