Answer 1

DVD cases 20/pack
Envelopes 12/pack

20 12
40. 24
60. 36
48
60
3 packs of DVD cases
5 packs of envelopes

Answer 2

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

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

`(60)/(20)=3`

Minimum number of padded mailing envelopes is given by

`(60)/(12)=5`

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