Enter proportion values below:

  
---------- ----------
  
  

You entered the following equivalent proportions:

-8
9x
>
  
-61
81

Define the proportion formula:

If 2 proportions are equal:
we can cross multiply to get:

Numerator 1
Denominator 1
>
  
Numerator 2
Denominator 2

Numerator 1 * Denominator 2 > Denominator 1 * Numerator 2

Solving for Denominator 1 we get:

Denominator 1  >  Numerator 1 * Denominator 2
  Numerator 2

Evaluate and simplfy

9x  >  -8 * 81
  -61

9x  >  -648
  -61

9x  >  10.622950819672

Divide each side by 9

Because we have an inequality and we are dividing by a positive number, we keep the same sign >

9x
9
>
  
10.622950819672
9

Final Answer



x > 1.1803278688525



What is the Answer?
x > 1.1803278688525
