Question

помогите пожалуйста​

Answer 1

1)5/6+1/6=6/6=1

2)5,8/2,5=2,32

Answer 2

$\frac{5}{6} + \frac{7}{12} \times \frac{2}{7} = \frac{5}{6} + \frac{1}{6} = \frac{6}{6} = 1 \\ \frac{2.6 - 8.4}{2.5} = \frac{5.8}{2.5} = \frac{58}{10} \div \frac{25}{10} = \frac{58 \times 10}{10 \times 25} = \frac{58}{25} = \frac{58 \times 4}{25 \times 4} = \frac{232}{100} = 2.32$
