Question

4/x=12/66,4:0,8=x:10x/125=4/5SOS.SOS.SOS​

Answer 1

4/х = 12/6 - это пропорция

х · 12 = 4 · 6 - свойство пропорции

х · 12 = 24

х = 24 : 12

х = 2

- - - - - - - - - -

6,4 : 0,8 = х : 10 - это пропорция

0,8 · х = 6,4 · 10 - свойство пропорции

0,8 · х = 64

х = 64 : 0,8

х = 80

- - - - - - - - - -

х/125 = 4/5 - это пропорция

х · 5 = 125 · 4 - свойство пропорции

х · 5 = 500

х = 500 : 5

х = 100

Answer 2

It looks like you've written a series of equations and expressions. Let's break them down one by one:

1. 4/x = 12/66: To solve for x, you can cross-multiply and then divide: 4/x = 12/66 4 * 66 = 12 * x 264 = 12x x = 264 / 12 x = 22

2. 4:0: In mathematics, division by zero is undefined. So, 4 divided by 0 is undefined or infinite.

3. 8 = x: This equation is straightforward. It says that x equals 8.

4. 10x/125 = 4/5: To solve for x, you can cross-multiply and then divide: 10x/125 = 4/5 10x * 5 = 4 * 125 50x = 500 x = 500 / 50 x = 10

So, the solutions to these equations are:

1. x = 22
2. Division by zero is undefined.
3. x = 8
4. x = 10

It's not clear what you mean by "SOS.SOS.SOS" at the end, so I can't provide any interpretation for that part. If you have any further questions or need clarification, please let me know.
