Answer 2

To solve this expression, let's break it down step by step:

First, let's simplify the expression inside the parentheses: 2,6 * 0,3 = 0,78 2 целых 4 пятнадцатый = 2 + (4/15) = 2 + 0,2666... = 2,2666...

Next, let's divide the numerator by the denominator: 0,78 - 2,2666... = -1,4866...

Finally, let's divide the result by -1.9: -1,4866... / -1.9 = 0,7824...

Therefore, the result of the expression is approximately 0.7824.
