Uang andi 1 2/3 dr uang banu. Selisih uang mereka 12.500. Jumlah mereka adalah

a = andi
b = banu

ditanya : a+b

jwb :

a = 1 2/3 b
a - b = 12.500
1 2/3 b - b = 12.500
2/3 b = 12.500
b = 12.500 : 2/3
b = 12.500 × 3/2
b = 18.750

a = 1 2/3 b
a = 1 2/3 (18.750)
a = 5/3 (18.750)
a = 31.250

a + b = 31.250 + 18.750 = 50.000

semoga membantu
