(2) Four sisters love barrettes. They have a value pack that contains 92 barrettes. How many barrettes can each sister have if they share equally? Estimate: Number model with unknown Answer: barrette(s)

If the four sisters share the 92 barrettes equally, we can represent the situation with the equation: 92 ÷ 4 = x, where x is the number of barrettes each sister will receive. As for estimation, you can round 92 to 100, making it easier to see that each sister would roughly receive about 25 barrettes. Now, solving the equation: 92 ÷ 4 = 23. Therefore, if they share equally, each sister will get 23 barrettes. So, the answer is 23 barrettes per sister!
