Answer 2

It seems you have written two equations:

1. 720 : x = 80
2. x : 30 = 420

Let's solve each equation step-by-step:

1. 720 : x = 80

To solve this equation for x, we need to isolate x on one side of the equation. In order to do that, we can cross-multiply:

720 * 1 = 80 * x

Simplifying further:

720 = 80x

Now, divide both sides of the equation by 80 to solve for x:

x = 720 / 80 x = 9

So, the value of x is 9.

2. x : 30 = 420

To solve this equation for x, again, we need to isolate x on one side. We can cross-multiply:

x * 1 = 30 * 420

Simplifying further:

x = 30 * 420

Now, perform the multiplication:

x = 12600

So, the value of x is 12600.

Please double-check your original equations and calculations to ensure they are accurate. If you meant something else, feel free to clarify, and I'd be happy to help.
