Answer 2

Ответ:

1) 14/20. 2) 22//2.

Пошаговая объяснение:

1)5/6+9/14=14/20.

2)57/8-35/6=22/2.

Answer 3

Sure, let's solve these expressions step by step.

1. $\left| \frac{5}{6} \right| + \left| -\frac{9}{14} \right|$

First, find the absolute values: $\left| \frac{5}{6} \right| = \frac{5}{6}$ $\left| -\frac{9}{14} \right| = \frac{9}{14}$

Now, add them: $\frac{5}{6} + \frac{9}{14}$

To add these fractions, we need to find a common denominator, which is the least common multiple (LCM) of 6 and 14, which is 42.

$\frac{35}{42} + \frac{27}{42} = \frac{62}{42}$

Now, simplify the fraction: $\frac{62}{42} = \frac{31}{21}$

So, $\left| \frac{5}{6} \right| + \left| -\frac{9}{14} \right| = \frac{31}{21}$

2. $\left| -\frac{5}{8} \right| - \left| -\frac{3}{6} \right|$

First, find the absolute values: $\left| -\frac{5}{8} \right| = \frac{5}{8}$ $\left| -\frac{3}{6} \right| = \frac{1}{2}$

Now, subtract them: $\frac{5}{8} - \frac{1}{2}$

To subtract these fractions, we need a common denominator, which is 8 in this case.

$\frac{5}{8} - \frac{4}{8} = \frac{1}{8}$

So, $\left| -\frac{5}{8} \right| - \left| -\frac{3}{6} \right| = \frac{1}{8}$
