Question

X/10=2/4? or x over 10 equals to 2 over 4

Answer 1

The answer is:  " x = 5 " .
_______________________________________________
Note the following:
_______________________________________________

2/4 = 1/2 ; 

1/2 = (1*5) / (2*5) = 5/10 ; 

2/4 = 1/2 = 5 / 10 . 

or:  2/4 = 1/2 = 0.5 = 5/ 10 .  

The answer:  " x = 5 " .

Or:  x/ 10 = 2/4 ;  

Cross-multiply:

  4x = (2)(10) ; 

  4x = 20 ; 

Divide each side by "4" ; 

  4x / 4 = 20/4 ; 

   " x = 5 " ;

Or:  x/10 = 2/4 ; 

Note:  "2/4 = 1/2" ;  so rewrite as:

x/10 = 1/2 ; and cross-multiply:

2x = (10)(1) ; 

2x = 10 ; 

Divide each side of the equation by "2" ; 

2x / 2 = 10 / 2 ; 

  " x = 5 " .
