Question

a board game has a spinner divided into sections of equal size. Each section is labled with a number between 1 and 5. Which number is a reasonable estimate of the number of times the spinner will land on a section labled 5 over the course of 150 spins?

Hi there! 

In order to solve this problem, we can use a couple proportions. First, we'll use this proportion: 1/5 = x/150. Now, cross-multiply: 5x = 150. Then, divide: x = 30. This means that the spinner will hit the section labeled 5, 30 out of 150 times. Now we need to find the percentage. To find the percentage, we'll use this proportion: 30/150 = x/100. Cross-multiply: 150x = 3000. Divide: x = 20. This means that the spinner will land on the section labeled 5, 30 out of 150 times or 20% of the time.

Hope this helps!! :)
