Sofia wants to place a sticker 2 ½ inches long in the center of a switch box that is 3 ¾ inches wide. about how far from the edge will she place the sticker?

3 3/4 -2 1/2=
15/4-5/2=
15/4-5/2*2/2=
15/4-10/4=
5/4=

5/4 divided by 2 (gives you the distance from the edge if you put the sticker in the center)

5/4 / 2/1=5/8 inches from the edge

I think this is correct. Hope it helps
