Answer 1

как-то так, надеюсь понятно

Answer 2

To simplify the expression, let's perform the operations step by step:

Step 1: Convert all the fractions to a common denominator: We can choose the common denominator as 12 since it is a multiple of 6, 12, and 2.

5/6 + 7/12 = (5 * 2)/(6 * 2) + 7/12 = 10/12 + 7/12 = 17/12

Step 2: Perform the addition and subtraction operations:

(17/12) - (1/3) * (6/5) - (5/6) * (2/252) = 17/12 - 1/3 * 6/5 - 5/6 * 2/252

Step 3: Perform the multiplication:

1/3 * 6/5 = (1 * 6)/(3 * 5) = 6/15 = 2/5

5/6 * 2/252 = (5 * 2)/(6 * 252) = 10/1512 = 5/756

Now the expression becomes:

17/12 - 2/5 - 5/756

Step 4: Convert all fractions to a common denominator again:

Since 12 is also a multiple of 5 and 756, we can use it as the common denominator.

17/12 - 2/5 - 5/756 = (17 * 63)/(12 * 63) - (2 * 1512)/(5 * 1512) - 5/756

Step 5: Perform the subtraction:

(17 * 63)/(12 * 63) - (2 * 1512)/(5 * 1512) - 5/756 = (1071 - 3024 - 5) / 756 = -1958 / 756

Step 6: Reduce the fraction to its simplest form:

-1958 / 756 = -(1958/2) / (756/2) = -979 / 378

Now let's proceed with the next part of the expression:

5 * 3.5 - 0.352 + 1 * 3.5 / (4.9400 * 0.004 * 40)

Step 1: Perform the multiplication and addition:

5 * 3.5 = 17.5 1 * 3.5 = 3.5

Now the expression becomes:

17.5 - 0.352 + 3.5 / (4.9400 * 0.004 * 40)

Step 2: Perform the division and multiplication:

4.9400 * 0.004 * 40 = 0.7872

Now the expression becomes:

17.5 - 0.352 + 3.5 / 0.7872

Step 3: Perform the division:

3.5 / 0.7872 ≈ 4.44 (rounded to two decimal places)

Now the expression becomes:

17.5 - 0.352 + 4.44

Step 4: Perform the subtraction:

17.5 - 0.352 + 4.44 ≈ 21.588 (rounded to three decimal places)

Putting it all together, the simplified expression is approximately:

-979 / 378 + 21.588 ≈ 20.152 (rounded to three decimal places).
