Solution steps

(4 \cdot 0.2) + (\frac{1}{5}) - (1 - 0.9) \frac{1}{2}

(4 \cdot 0.2) + (\frac{1}{5}) - (1 - 0.9) \frac{1}{2} = 4 \cdot 0.2 + \frac{1}{5} - (1 - 0.9) \frac{1}{2}

= 4 \cdot 0.2 + \frac{1}{5} - (1 - 0.9) \frac{1}{2}

4 \cdot 0.2 = 0.8

(1 - 0.9) \frac{1}{2} = \frac{1}{20}

= 0.8 + \frac{1}{5} - \frac{1}{20}

0.8 + \frac{1}{5} - \frac{1}{20} = \frac{19}{20}

= \frac{19}{20}
