Answer 1

Ответ:

Пошаговое объяснение:

(7-1. 5/12):6,7+(5,75-3 1/6):15,5=1.

По действиям:

1)  7-1 5/12 = 6 - 5/12 = 5 12/12 - 5/12 = 5 7/12;

2)  5 7/12:6.7= 67/12 : 67/10 = 67/12 * 10/67 = 5/6;

3)  5,75-3 1/6=5 3/4-3 1/6=>НОК(4;6)=12=>5 9/12 - 3 2/12 = 2 7/12;

4)  2 7/12 : 15.5=31/12 : 155/10=31/12 : 31/2=31/12 * 2/31=1/6;

5)  5/6 + 1/6 = 6/6=1.

Answer 2

Let's break down and calculate the expressions step by step:

1. 7 - 1 = 6

2. 5/12 = 0.41666666667 (rounded to 10 decimal places)

3. Now, we subtract 0.41666666667 from 6:

   6 - 0.41666666667 ≈ 5.58333333333 (rounded to 10 decimal places)

So, the result of (7 - 1. 5/12) divided by 6 is approximately 5.58333333333.

Next, let's work on the second expression:

1. 5.75 - 3 = 2.75

2. 1/6 = 0.16666666667 (rounded to 10 decimal places)

3. Now, we subtract 0.16666666667 from 2.75:

   2.75 - 0.16666666667 ≈ 2.58333333333 (rounded to 10 decimal places)

So, the result of (5.75 - 3 1/6) divided by 15.5 is approximately 2.58333333333.

Now that we have both results:

1. (7-1. 5/12):6 ≈ 5.58333333333
2. (5.75-3 1/6):15.5 ≈ 2.58333333333

These are the approximate values of the two expressions.
