Solve (432*10^-1)-(25*10^-1)quad115

$$( 432 \times 10 ^ { - 1 } ) - ( 25 \times 10 ^ { - 1 } ) \quad 115$$

Evaluate

$$-\frac{2443}{10}=-244.3$$

Solution Steps

Calculate 10 to the power of -1 and get \frac{1}{10}.

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

Multiply 432 and \frac{1}{10} to get \frac{216}{5}.

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

Calculate 10 to the power of -1 and get \frac{1}{10}.

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

Multiply 25 and \frac{1}{10} to get \frac{5}{2}.

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

Multiply \frac{5}{2} and 115 to get \frac{575}{2}.

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

Subtract \frac{575}{2} from \frac{216}{5} to get -\frac{2443}{10}.

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

Factor

$$-\frac{2443}{10} = -244\frac{3}{10} = -244.3$$
