The aspect ratio of a laptop monitor is 1.625:1 . The aspect ratio of a monitor is the ratio of its worth to its height. Write t

Artemon [7]

Answer:

Part 1) The ratio is $\frac{13}{8}$

Part 2) The height is 9.23 in

Step-by-step explanation:

Part 1)

Let

x ----> the wide of the monitor

y ----> the height of the monitor

z ----> the aspect ratio of a laptop monitor

$z=\frac{x}{y}$

we have

$z=\frac{1.625}{1}$

Multiply both numerator and denominator by 1,000

$z=\frac{1.625*1,000}{1*1,000}$

$z=\frac{1,625}{1,000}$

Simplify

Divide by 125 both numerator and denominator

$z=\frac{13}{8}$

Part 2) If the Monitor is 15 inches wide, what is the height?

we know that

$z=\frac{x}{y}$

we have

$z=\frac{13}{8}$

$x=15\ in$

substitute the given values and solve for y

$\frac{13}{8}=\frac{15}{y}$

$y=\frac{8}{13}(15)$

$y=9.23\ in$

therefore

The height is 9.23 in
