Answer 2

а) |-3.6|:|-18|=3,6:18=0,2

б) |1 5\9|*|-1 2/7|=1 5/9*1 2/7=14/9*9/7=2

Answer 3

Let's evaluate the expressions step by step:

а) $-3 \frac{6}{-18}$

To evaluate this expression, first, divide $6$ by $-18$, which gives us $-\frac{1}{3}$. Then, add $-3$ to the result:

$-3 + \left(-\frac{1}{3}\right) = -3 - \frac{1}{3} = -\frac{10}{3}$

So, the value of the expression is $-\frac{10}{3}$.

б) $\left|\frac{1}{5/9}\right| \times \left|-1 \frac{2}{7}\right|$

To simplify this expression, first, find the value inside each absolute value:

$\frac{1}{5/9} = \frac{1}{\frac{5}{9}} = \frac{9}{5}$

$-1 \frac{2}{7} = -\frac{9}{7}$

Now, multiply the two absolute values together:

$\left|\frac{9}{5}\right| \times \left|-\frac{9}{7}\right| = \frac{9}{5} \times \frac{9}{7} = \frac{81}{35}$

So, the value of the expression is $\frac{81}{35}$.

In conclusion, the values of the expressions are:

а) $-\frac{10}{3}$

б) $\frac{81}{35}$
