Пошаговое объяснение:

1)

3. 1/6 + 1. 1/8 - 2. 1/4 =

3. 4/24 + 1. 3/24 - 2. 6/24 =

4. 7/24 - 2. 6/24 = 2. 1/24

2)

-5. 1/16 + 1. 1/8 = -5. 3/48 + 1. 6/48 =

-4. 51/48 + 1. 6/48 = -3. 45/48 =

-3. 15/16

х + 19 = 12

х = 12 - 19

х = -7

-25 - х = -17

х = -25 - (-17)

х = -25 + 17

х = -8

Answer 3

1.1) To solve the expression 3 1/6 + 1 1/8 - 2 1/4, we need to convert all the mixed numbers into improper fractions.

3 1/6 can be written as (3 * 6 + 1) / 6 = 19/6 1 1/8 can be written as (1 * 8 + 1) / 8 = 9/8 2 1/4 can be written as (2 * 4 + 1) / 4 = 9/4

Now we can substitute these values back into the expression and simplify:

19/6 + 9/8 - 9/4

To add fractions, we need a common denominator, which in this case is 24.

(19/6) * (4/4) = 76/24 (9/8) * (3/3) = 27/24 (9/4) * (6/6) = 54/24

Now we can rewrite the expression with the common denominator:

76/24 + 27/24 - 54/24

Combining the numerators:

76 + 27 - 54 = 49

The final result is 49/24.

2. To solve the equation x + 19 = 12, we can isolate x by subtracting 19 from both sides of the equation:

x + 19 - 19 = 12 - 19

This simplifies to:

x = -7

The solution to the equation is x = -7.

To solve the equation -25 - x = -17, we can isolate x by adding 25 to both sides of the equation:

-25 - x + 25 = -17 + 25

Simplifying:

x = 8

The solution to the equation is x = 8.
