Question

2/9×0,625×4,5+0,175
-------------------------‐----
6/7×2 1/3-1 1/6×6/7

Answer 1

Ответ:

$\frac{2}{9} \times 0.625 \times 4.5 + 0.175 = \frac{2}{9} \times \frac{625}{1000} \times \frac{45}{10} + \frac{175}{1000} = \frac{56250}{90000} + 0.175 = 0.625 + 0.175 = 0.8 \\ \frac{6}{7} \times \frac{7}{3} - \frac{7}{6} \times \frac{6}{7} = 2 - 1 = 1$
