Anastasia is grocery shopping with her father and wonders how much shopping is left to do. "We already have 60\%60%60, percent of the items on our list," her father says. Anastasia sees 121212 items in the cart.
How many grocery items are on the list?
+129849 I'm assuming that the numbers are supposed to be "60%" and "12" ....if so
12 = 60% of the total items to be purchased.......so....using a proportion, we have
12/60 = N / 100 where N is the total items on the list
1/5 = N / 100 cross-multiply
100/5 = N = 20 items to be purchased
