Q. If the 8 men on a construction crew make up 40% of the entire crew, how many people are in the crew?
Understand the problem: Understand the problem.We are given that 8 men make up 40% of the construction crew. We need to find the total number of people in the crew.
Set up the equation: Set up the equation.Let the total number of people in the crew be x. According to the problem, 40% of x is equal to 8 men.So, we can write the equation as 0.40×x=8.
Solve for x: Solve for x.To find x, we divide both sides of the equation by 0.40.x=0.408
Calculate total number: Calculate the total number of people in the crew. x=0.408x=20
Verify the solution: Verify the solution.If there are 20 people in the crew and 8 men make up 40% of it, then 40% of 20 should be 8.0.40×20=8This is true, so our solution is correct.
