Irma's Diner sold 20 milkshakes last week. 30% of the milkshakes had whipped cream on top. How many milkshakes with whipped cream were sold?

Answer 1

To find out how many milkshakes had whipped cream on top, we can calculate 30% of the total number of milkshakes sold, which is 20.

First, convert the percentage to a decimal: $$30$$

Now, multiply the total number of milkshakes by the decimal: $$0.30\times 20=6$$

Therefore, Irma's Diner sold 6 milkshakes with whipped cream on top.
