Question

Rezultatul calculului 5 supra 8 - 3 supra 4 x 0,1(6) .

Answer 1

$\frac{5}{8} - \frac{3}{4} \times 0.1(6) = \frac{5}{8} - \frac{3}{4} \times \frac{16 - 1}{90}$

$= \frac{5}{8} - \frac{3}{4} \times \frac{15}{90} = \frac{5}{8} - \frac{3}{4} \times \frac{3}{18}$

$= \frac{5}{8} - \frac{3}{4} \times \frac{1}{6} = \frac{5}{8} - \frac{3}{24}$

$= \frac{15}{24} - \frac{3}{24} = \frac{12}{24} = \frac{1}{2}$
