ПОЖАЛУЙСТА ПОМОГИТЕ!!! 5 1/7-( 5,7 : 3 + 1 7/9) =

Answer 1

$\frac{51}{7} - (5.7 \div 3 + \frac{17}{9} ) \\ \frac{51}{7} - (1.9 + \frac{17}{9} ) \\ \frac{51}{7} - ( \frac{19}{10} + \frac{17}{9} ) \\ \frac{51}{7} - ( \frac{171 + 170}{90} ) \\ \frac{51}{7} - \frac{341}{90} = \frac{2203}{630} = 3 \frac{313}{630}$
