Answer 2

Ответ: $\frac{2-2a}{a} = \frac{2}{a} -2$

Решение:

$((\frac{4a}{2} - a)-a):a+\frac{2}{a} - 2 = (2a - a - a):a + \frac{2}{a} - \frac{2a}{a} = \frac{0}{a} +\frac{2}{a} -\frac{2a}{a} = \frac{2-2a}{a} = \frac{2}{a} -2$

Answer 3

Let's break down the expression step by step:

((4a/2-a) -a)/a + 2/a - 2

First, simplify the expression within the innermost parentheses:

(4a/2 - a) = 2a - a = a

Now, the expression becomes:

(a - a)/a + 2/a - 2

The numerator in the first fraction is 0, so we have:

0/a + 2/a - 2

To add fractions, we need a common denominator. In this case, the common denominator is "a". So, we rewrite the expression:

0/a + (2/a) - (2a/a)

Simplifying further:

0/a + 2/a - 2a/a = 2/a - 2a/a

Now, we can subtract the fractions with the same denominator:

(2 - 2a)/a

Thus, the simplified expression is:

(2 - 2a)/a

Note: It's important to remember that division by zero (a = 0 in this case) is undefined. So, if "a" equals zero, the expression is undefined.
