Answer 1

Пошаговое объяснение:

-9/14*21/45= - 21/70

-5+0,06=-4,94

-21/70:(-4,94) =15/247

Answer 2

To solve this expression, you should follow the order of operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders (i.e., powers and square roots, etc.), Multiplication and Division (left-to-right), and Addition and Subtraction (left-to-right).

Let's break down the expression step by step:

-9/14 * 21/45 / (-5 + 0.06)

1. Calculate the values inside the parentheses: -5 + 0.06 = -4.94

2. Now, calculate the multiplications and divisions from left to right: -9/14 * 21/45 / -4.94

3. Calculate each multiplication and division: (-9/14) * (21/45) = -0.675

4. Now, divide the result by -4.94: -0.675 / -4.94 = 0.1364 (rounded to four decimal places)

So, the final result is approximately 0.1364.
