Q. Anastasia is grocery shopping with her father and wonders how much shopping is left to do. "We already have 60%60\% of the items on our list," her father says. Anastasia sees 1212 items in the cart. How many grocery items are on the list?
  1. Identify part and percentage: Identify the part and the percentage to find the whole.\newlineHere, 60%60\% of the total items equals 1212 items.\newlineCalculation: Let the total number of items be xx.\newline60%60\% of x=12x = 12\newline0.6×x=120.6 \times x = 12
  2. Calculate total items: Solve for xx by isolating it.\newlineDivide both sides by 0.60.6 to find xx.\newlinex=120.6x = \frac{12}{0.6}\newlinex=20x = 20
