Answer 1

Explicație pas cu pas:

a)

$a = 1.5 = \frac{15}{10} = \frac{2}{3} \\ \frac{a}{b} = \frac{ \frac{2}{3} }{ \frac{1}{3} } = \frac{2}{3} \times 3 = 2$

b)

$2a - b = 2 \times \frac{1}{3} - \frac{2}{3} = \frac{2}{3} - \frac{2}{3} = 0$

$2a + b = 2 \times \frac{2}{3} + \frac{1}{3} = \frac{5}{3}$
