R. Problem Solving with Decimals

Choose a strategy to solve each problem. Use pages in the Student Guide Reference section.

  1. A cheeseburger from a popular fast-food restaurant has 5.7 grams of saturated fat. If you eat 21/2 cheeseburgers, how much saturated fat will you eat?
  2. A small order of onion rings can have as much as 67.5 milligrams of sodium (salt). How many milligrams can be in a 1/2 serving?
  3. One batch of french fries from a well-known fast food restaurant contains 17.7 grams of fat. If you eat 3 orders, how much fat will you eat?
  4. One serving of potato chips has 10.1 grams of fat. The whole bag of chips holds 12 servings. If you eat the whole bag, how may grams of fat have you eaten?
  5. Three breadsticks have 1.5 grams of fat. How much fat do 5 breadsticks have? Show or tell how you solved this.
