width = 16.9 inches !

Step-by-step explanation:

Here we have , The length to width ratio of wide-screen televisions is 16:9. If a TV is 30 inches  long, We need to find how wide is it . Let's find out:

length to width ratio of wide-screen televisions is 16:9 And , length of TV is 30 inches is 30 . Let width be x inches so , According to question we have following equation framed as :

[tex]\frac{16}{9} =\frac{30}{x}[/tex]

⇒[tex]\frac{16}{9}(x) =\frac{30}{x}(x)[/tex]

⇒[tex]\frac{16}{9}(x) =30[/tex]

⇒[tex]\frac{16}{9}(x)(\frac{9}{16} ) =30)(\frac{9}{16} )[/tex]

⇒[tex]x=30(\frac{9}{16} )[/tex]

⇒[tex]x=(\frac{30(9)}{16} )[/tex]

⇒[tex]x=\frac{270}{16}[/tex]

⇒[tex]x=16.9inches[/tex]

Therefore , width = 16.9 inches !
