1. Relacionamos os números a, b c k
a = 3k
b = 5k
c = 7k
2. Utilizamos a soma dos números para encontrark
3k + 5k + 7k = 54
15k = 54
k = 3.6
3. Calculamos os valores dos números:
a = 3k = 10.8
b = 5k = 18
c = 7k = 25.2
Portanto, os valores são:
a = 10.8 b = 18 c = 25.2
2. Utilizamos a soma dos números para encontrar
3. Calculamos os valores dos números:
Portanto, os valores são:
