Jorge wants to determine the enlarged dimensions of a digital photo to be used as wallpaper on his computer screen. The original
photo was 800 pixels wide by 600 pixels high. The new photo will be 1,260 pixels wide. What will the new height be?
460 pixels
945 pixels
1,680 pixels
1,860 pixels

945

Step-by-step explanation:

We should calculate how much did the pixels increase from the old width to the new width and to do that we should do as follows:

1260/800 = 1.575

Now that we found that the new width is 1.575 times more than the old one so we use that to multiply that to the original height.

1.575 x 600 = 945

900 degrees
