Lisa had 60 lollies to share. She gave each of her friends the same number of lollies and had 5 left over for herself. If Lisa had fewer lollies than any of her friends, how many friends did Lisa share her lollies with?
Let f be the number of friends and n be the number of lollies each one gets.
Now we know the number of friends multiplyied by how many lollies +5 must equal 60.
$\displaystyle 60=f\cdot n+5$
now we subtract 5 from both sides to get
$\displaystyle 55=f \cdot n$
We also know that her friends each got more lollies then her so n > 5
55 has only two factors $\displaystyle 55 = 5 \cdot 11$
So n must be 11 and f must be 5.
So she has five friends and each of them got 11 lollies.
I hope this helps.
