Respuesta :
The least common multiple of 25 and 15 is 75. You'd do _ x 25 = 75 and _ x 15 = 75. The answer would be 3 and 5, so 5 packs of coins and 3 packs of coin holders.
Answer:
5 packs of commemorative coins and 3 packs of coin holders.
Step-by-step explanation:
We have been given that commemorative coins come in packs of 15,while coin holders come in packs of 25.
To find the least number of packs, we need to find LCM of 15 and 25.
Multiples of 15: 15, 30, 45, 60 ,75, 90,..
Multiples of 25: 25, 50, 75, 100,...
We can see that least common multiple of 15 and 25 is 75.
[tex]\text{Packs of commemorative coins}=\frac{75}{15}=5[/tex]
[tex]\text{Packs of coin holders}=\frac{75}{25}=3[/tex]
Therefore, you should buy 5 packs of commemorative coins and 3 packs of coin holders.
