A computer disk holds 4 1/2 GB. If you put 5 files of size 2/3 GB each, and 5 files of size 1/6 GB each onto this disk, how much space is left as a fraction?

unclear question

as a fraction itself, or as a fraction of the disk?

Explicație pas cu pas:

4 1/2-5*(2/3)-5*(1/6)=

9/2-10/3-5/6=

27/6-20/6-5/6=2/6=1/3 GB as a (fractional) number

if  you want as a fraction of the disk, than

(1/3)GB/(9/2)GB =(1/3) *(2/9)=2/27
