Answer: The required ratio is 1:1.

Explanation:

Let the total number of CDs be 100


(1)/(10) of CDs is given by


(1)/(10)* 100\\\\=10

According to question,


(1)/(5) of her Jazz CDs represents
(1)/(10) of all her CDs.

Let the number of Jazz CDs be x

So, it becomes


(1)/(5)* x=10\\\\x=10* 5\\\\x=50

So, Number of Jazz's CDs is 50

Number of Jazz non CDs is given by


100-50=50

Ratio of her CDs to her non- CDs is given by


50:50\\\\1:1

Hence, the required ratio is 1:1.
