Douglas Stationery sells cards in packs of 6 and envelopes in packs of 8. If Jesse wants the same number of each, what is the minimum number of cards that he will have to buy?

The minimum number of cards that Jesse will have to buy is 24.

Step-by-step explanation:

We are given that Douglas Stationery sells;

cards in packs of 6

envelopes in packs of 8

We want to find the minimum number of cards If Jesse wants the same number of each.

This can be found by taking the least common multiple (LCM) of the pack of cards and pack of envelops.

LCM by division:

  | 6, 8

2 | 3, 4

2 | 3, 2

2 | 3, 1

3 | 1, 1

So the LCM is

LCM = 2*2*2*3

LCM = 24

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
