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 " .
