Question

7y-3 2/9y+6 1/18y упростите пожалуйста

Answer 1

$7y - 3 frac{2}{9} y + 6 frac{1}{18} y = \ 6 frac{9}{9} y - 3 frac{2}{9} y + 6 frac{1}{18} y = 9 frac{5}{6} y$
$6 frac{9}{9} - 3 frac{2}{9} = 3 frac{7}{9} + 6 frac{1}{18} = \ = 3 frac{14}{18} + 6 frac{1}{18} = 9 frac{15}{18} = 9 frac{5}{6}$
