Final answer:
Beth has 19 friends. She originally had 59 lollipops, and after giving away groups of three and having 2 left, the division shows that she gave away lollipops to 19 friends.
Step-by-step explanation:
This asks us to determine how many friends Beth has if she won 59 lollipops, and after giving them away in groups of three, she has 2 left. To find the answer, we perform a simple division operation followed by subtracting the remainder to find the total number of friends. We start with 59 lollipops. If Beth has 2 lollipops remaining after giving them away, she gave away 59 - 2 = 57 lollipops. Since each friend received 3 lollipops, we divided the total number of given-away lollipops by 3 to find the number of friends. That is 57 ÷ 3 = 19 friends. Therefore, Beth has 19 friends.
