A cabinet has shelves that are 11 1/2 in. Apart. On one shelf, brad stacked a cd player that is 5 1/4 in. High on top of an amplifier that is 4 1/8 in. High. How much space is left above the cd player?

Step-by-step explanation:

Given the total space in the shelf = 11 1/2 in

Total spaced used = 5 1/4 + 4 1/8

Total spaced used = 21/4 + 33/8

Total spaced used = 42+66/16

Total spaced used = 108/16

Total spaced used = 6 12/16

Total spaced used = 6 3/4 in

Amount of space left = 11 1/2 - 6 3/4

Amount of space left = 23/2 - 27/4

Amount of space left = (46-27)/4

Amount of space left = 19/4

Amount of space left = 4 3/4 in

Hence the amount of space left in the shelf is 4 3/4 inches
