The value of $$0.4\overline{7} + 0.5\overline{03} - 0.3\overline{9} \times 0.\overline{8}$$ is:

Solution

$$0.4\overline{7} + 0.5\overline{03} - 0.3\overline{9} \times 0.\overline{8}$$
= $$\frac{47 - 4}{90}+ \frac{503 - 5}{990} - \frac{39 - 3}{90} \times \frac{8}{9}$$
= $$\frac{43}{90}+ \frac{498}{990} - \frac{36}{90} \times \frac{8}{9}$$
= $$\frac{43}{90}+ \frac{498}{990} - \frac{32}{90}$$
= $$\frac{619}{990}$$
= $$0.6\overline{25}$$
