Question

помогите пожалуйста​

Answer 1

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

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

Answer 2

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