Jackson stationary sells cards in packs of 11 and envelopes in packs of 13. if kina wants the same number of each, what is the minimum number of cards she will have to buy?

143

Step-by-step explanation:

We are given that

Jackson stationary sells cards in one  pack=11

Number of  envelops in one pack=13

We  have to determine the minimum number of cards bought by Jackson if if she wants the same number of each .

In order to find the minimum number of cards then we will find the lcm of 11 and 13.

Hence, LCM of (11,13)=143

Therefore, the minimum number of cards bought by Jackson=143
