Passos Para a Resolução

Calcule 10 elevado a -1 e obtenha \frac{1}{10}.

$$432\times \frac{1}{10}-25\times 10^{-1}\times 115$$

Multiplique 432 e \frac{1}{10} para obter \frac{216}{5}.

$$\frac{216}{5}-25\times 10^{-1}\times 115$$

Calcule 10 elevado a -1 e obtenha \frac{1}{10}.

$$\frac{216}{5}-25\times \frac{1}{10}\times 115$$

Multiplique 25 e \frac{1}{10} para obter \frac{5}{2}.

$$\frac{216}{5}-\frac{5}{2}\times 115$$

Multiplique \frac{5}{2} e 115 para obter \frac{575}{2}.

$$\frac{216}{5}-\frac{575}{2}$$

Subtraia \frac{575}{2} de \frac{216}{5} para obter -\frac{2443}{10}.

$$-\frac{2443}{10}$$

Fatorizar

$$-\frac{2443}{10} = -244\frac{3}{10} = -244,3$$
