Answer 1

Ответ:

Пошаговое объяснение:

1)

-5. 4/9 - (-13) = -5. 4/9 + 13 = -5. 4/9 +

12. 9/9 = 7. 5/9

2)

-19. 1/2 + 21 = -19. 1/2 + 20. 2/2 = 1. 1/2

3)

6. 4/5 * 15/17 = 34/5 * 15/17 = 2/1 * 3/1 = 6/1 = 6

4)

5/7 : (-10. 5/49) = 5/7 : (-495/49) =

5/7 * (-49/495) = 1/1 * (-7/99) = -7/99

Answer 2

Пошаговое объяснение:

1.

-5. 4/9 - (-13) = -5. 4/9 + 13 = -5. 4/9 +

12. 9/9 = 7. 5/9

2.

-19. 1/2 + 21 = -19. 1/2 + 20. 2/2 = 1. 1/2

3.

6. 4/5 * 15/17 = 34/5 * 15/17 = 2/1 * 3/1 = 6/1 = 6

4.

5/7 : (-10. 5/49) = 5/7 : (-495/49) =

5/7 * (-49/495) = 1/1 * (-7/99) = -7/99

Answer 3

It looks like you have a math problem that needs solving. Let's break it down step by step.

Solving the Equations:

1. -5 4/9 - (-13) = -19 1/2 + 21 To solve this equation, we can simplify each side separately and then compare the results.

-5 4/9 - (-13) = -5 4/9 + 13 = 7 5/9 -19 1/2 + 21 = 1 1/2

So, the equation becomes: 7 5/9 = 1 1/2

This equation is not true, so there might be a mistake in the given equation.

2. 6 4/5 * 15/17 To solve this, we can multiply the two fractions.

6 4/5 can be converted to an improper fraction as (6 * 5 + 4)/5 = 34/5 So, the expression becomes: 34/5 * 15/17 = (34 * 15)/(5 * 17) = 510/85 = 6

Therefore, 6 4/5 * 15/17 = 6

3. 5/7 : (-10 + 5/49) To solve this, we need to first simplify the expression inside the parentheses and then perform the division.

-10 + 5/49 = -10 + 5/49 = -490/49 + 5/49 = -485/49 So, the expression becomes: 5/7 : (-485/49) = 5/7 * (-49/485) = -245/97

Therefore, 5/7 : (-10 + 5/49) = -245/97

I hope this helps! If you have any more math problems or any other questions, feel free to ask.
