Здравствуйте!

$\frac{1}{3}(2a - 9)-0.5(5b + 4)=\\=\frac{2}{3}a-3-2.5b-2=\\=\frac{2}{3}a-2.5b-5$

при а=4.5 и b=4/15

$\frac{2}{3}\times4.5-2.5\times\frac{4}{15}-5=\\\\=\frac{2\times45}{3\times10}-\frac{25\times4}{10\times 15}-5=\\\\=3-\frac{2}{3}-5=\\\\=2\frac{1}{3}-5=-2\frac{2}{3}$

Удачи в учебе.
