Question

3целых4/9+(8целых-d)=6целых5/9

Answer 1

$frac{4}{3} + 8 - d = frac{59}{9}$
$frac{28}{3} - d = frac{59}{9}$
$- d = frac{ - 25}{9}$
$d = frac{25}{9} = 2 times frac{7}{9}$
вроде так)))

Answer 2

$3 times frac{4}{9} + 8 - d = 6 times frac{5}{9}$
$11 times frac{4}{9} - d = 6 times frac{5}{9}$
$d = 11 times frac{4}{9} - 6 times frac{5}{9}$
$d = 4 times frac{8}{9}$
