Answer 1

32^2-256+16/29 : 320-40/29
32^2-240/29 : 280/29
32^2-240/29 : 29/280
(32^2-240) * 1/280
32^2/280 - 6/7
1024/280 : 6/7
14/5
2,8

Answer 2

$\frac{ {y}^{2} - 8y + 16 }{y - 3} \div \frac{10y - 40}{y - 3} = \\ = \frac{(y - {4)}^{2} }{y - 3} \times \frac{y - 3}{10(y - 4) } =$
$\frac{(y - 4)}{10} = \frac{32 - 4}{10} = \frac{28}{10} = 2.8$
