Question 1
You buy milk that contains 180 calories per 2 cups. Use a ratio table to find the number of calories in 18 cups.

The total number of calories for 18 cups of milk is 1620 calories.
If two cups of milk is 180 calories then divide 180/2 to find the unit rate.
Then multiply 90 by the number of cups (18) and then you get the total number of calories for that many drinks.
