Write a real-world problem in which it would be to find the least common multiple.

Here is one:

You go out to a grocery store to buy sausages and buns for a hot dog party you're hosting. Unfortunately, sausages come in a pack of 6, and buns in a pack of 8. 

What is the least number of sausages and buns you need to buy in order to make sure you are not left with a surplus of either sausages or buns? 

The answer is lcm(6, 8) = 24 for obvious reasons. You buy 4 packs of sausages, and 3 of buns. 

hope this helped 

have a nice evening

If there are four friends then each would get, 1.25 or 1 1/4. so this is how i solved 5 ÷ 4 = 1.25 . hope this ; )
