Solve (270*10^-2)-(12*10^-2)

$$(270 \times { 10 }^{ -2 } )-(12 \times { 10 }^{ -2 } )$$

Evaluate

$$\frac{129}{50}=2.58$$

Solution Steps

Calculate 10 to the power of -2 and get \frac{1}{100}.

$$270\times \frac{1}{100}-12\times 10^{-2}$$

Multiply 270 and \frac{1}{100} to get \frac{27}{10}.

$$\frac{27}{10}-12\times 10^{-2}$$

Calculate 10 to the power of -2 and get \frac{1}{100}.

$$\frac{27}{10}-12\times \frac{1}{100}$$

Multiply 12 and \frac{1}{100} to get \frac{3}{25}.

$$\frac{27}{10}-\frac{3}{25}$$

Subtract \frac{3}{25} from \frac{27}{10} to get \frac{129}{50}.

$$\frac{129}{50}$$

Factor

$$\frac{3 \cdot 43}{2 \cdot 5 ^ {2}} = 2\frac{29}{50} = 2.58$$
