Q. Anastasia is grocery shopping with her father and wonders how much shopping is left to do.
Understand Percentage Relationship: Understand the relationship between the percentage and the total number of items.Anastasia's father says they have 60% of the items on their list, which means that the 12 items in the cart represent 60% of the total number of items on the list.
Set Up Equation: Set up the equation to find the total number of items on the list. Let the total number of items on the list be represented by x. According to the percentage formula (Part = Percent × Whole), we have: 12=0.60×x
Solve for Total: Solve for x to find the total number of items on the list.Divide both sides of the equation by 0.60 to isolate x:x=0.6012
Perform Division: Perform the division to calculate the total number of items. x=0.6012x=20
Verify Solution: Verify that the solution makes sense.If there are 20 items on the list and they have 12 items in the cart, then 12 is indeed 60% of 20, which confirms that the calculation is correct.
