Answer 2

Let's solve each of these equations step by step:

1. x:11 = 77:7

To solve for x, you can cross-multiply:

x * 7 = 11 * 77

Now, isolate x:

x = (11 * 77) / 7

x = 847 / 7

x = 121

So, the solution is x = 121.

2. 4/x = 12/6

To solve for x, you can cross-multiply:

4 * 6 = 12 * x

24 = 12x

Now, isolate x:

x = 24 / 12

x = 2

So, the solution is x = 2.

3. 6.4:0.8 = x:10

In this equation, you can't divide by zero (0.8). Division by zero is undefined. Therefore, there is no valid solution for x in this equation.

4. x/125 = 4/5

To solve for x, you can cross-multiply:

x * 5 = 4 * 125

Now, isolate x:

x = (4 * 125) / 5

x = 500 / 5

x = 100

So, the solution is x = 100.

In summary:

1. x = 121
2. x = 2
3. No valid solution (division by zero is undefined).
4. x = 100
