Question

А) 3 2 / (3 4 -5 12) = д) 3- 2 3*6 7 дроби.

Answer 1

A) 3/4 - 5/12=4/12

3/2 / 4/12= 3/2 * 12/4 = 18/4
д)3 - 2/3=2 целых 1/3

2 целых 1/3*6/7=2

Answer 2

To solve the given expressions, let's take them one by one:

А) 3 2 / (3 4 -5 12)

First, let's clarify the expression as it seems ambiguous. I'll assume it means:

3 + 2 / (3 - 4 - 5 + 12)

Now, let's simplify the expression step by step:

1. Solve the brackets: 3 - 4 = -1 -1 - 5 = -6 -6 + 12 = 6

So the expression becomes:

3 + 2 / 6

2. Perform division: 2 / 6 = 1/3

Now, add the remaining terms:

3 + 1/3 = 3 1/3

Therefore, the result of the expression is 3 1/3.

д) 3 - 2 3 * 6 7 дроби

To clarify the expression, I assume it means:

3 - 2 * 3 + 6 / 7

Now, let's simplify the expression step by step:

1. Perform multiplication: 2 * 3 = 6

2. Perform division: 6 / 7 ≈ 0.8571 (rounded to four decimal places)

3. Perform subtraction: 3 - 6 ≈ -3

Now, the result of the expression is approximately -3.8571 (rounded to four decimal places).

Please double-check the expressions to make sure they were interpreted correctly. If there's any ambiguity or if the expressions differ, feel free to provide more context or clarify, and I'll be happy to help.
