multiplicar números decimais, efetuamos a operação como se fossem números
inteiros e no produto colocamos a vírgula, considerando o total de casas
decimais dos fatores.

Dicas para Divisão: Para dividir
números decimais, igualamos o número de ordens decimais do dividendo e do
divisor, eliminamos as vírgulas e efetuamos a divisão como se fossem números
inteiros.

Quando o
dividendo é menor que o divisor, colocamos zero e vírgula no quociente e zero à
direita do dividendo. Em seguida, efetuamos normalmente a divisão.
