Answer: There are 3 DVD and 5 padded mailing envelopes.

Step-by-step explanation:

Since we have given that

Number of DVD cases are sold = 20

Number of padded mailing envelopes = 12

We need to find the least number of cases and envelopes.

L.C.M. of 20 and 12 = 60

Minimum number of DVD cases is given by

$\dfrac{60}{20}=3$

Minimum number of padded mailing envelopes is given by

$\dfrac{60}{12}=5$

Hence, there are 3 DVD and 5 padded mailing envelopes.
