Grace [21]

Answer: 75\%

Step-by-step explanation:

You know that the ratio of the television's screen is 5:4 . This ratio can be also written as the following fraction:

\frac{5}{4}

The television shows an image with a ratio of 20:12 which can be also written as a fraction:

\frac{20}{12}

Set up the following proportion and solve for "x":

\frac{20}{x}=\frac{5}{4}\\\\x=\frac{4*20}{5}\\\\x=16

Now, in order to find the percent of the screen area occupied make the following division:

\% occupied=\frac{12}{16}*100=75\%
