$\frac{1}{2} - \frac{5}{4} + \frac{3}{25} = - 0.63$

#### Explanation:

$\frac{1}{2} - \frac{5}{4} + \frac{3}{25}$

= $\frac{1 \times 50}{2 \times 50} - \frac{5 \times 25}{4 \times 25} + \frac{3 \times 4}{25 \times 4}$

= $\frac{50}{100} - \frac{125}{100} + \frac{12}{100}$

= $0.50 - 1.25 + 0.12$

= $- 0.63$
