Sandy wants to email a picture file to a printing service. The picture has a 2736 pixel length and 3648 pixel width (common 3:4 ratio). If the image is to be cropped on the bottom to produce a 4:5 ratio for 8"x10" printing, how much pixel width (x) should be removed?

Original: 2736/3648=3/4

Cropped: 2736/3648-x=4/5

x=?

The given original picture that Sandy wants to email has a 2736 pixel length and 3648 pixel width (common 3:4 ratio).

The image needs to be cropped on the bottom to produce a 4:5 ratio.

Let the portion to be cropped on the bottom be x pixels.

So, according to the given condition:

`2736/(3648-x)=4/5`

`rArr 4(3648-x)=5*2736`

`rArr 14592-4x=13680`

`rArr 4x= 14592-13680`

`rArr x=912/4=228`

Therefore, pixel width (228) should be removed.
