Kitchen Math Workbook Shopping for the Kitchen Buying Large Quantities #11 Division, multiplication of decimals, subtraction of decimals Shopping for the Kitchen One way to save money is to buy food in large amounts. But you should be able to use the food you buy. And you must know how to compare quantities and costs. Example 1: The Coop Warehouse sells macaroni in 1.5 kg (or 1500 g) boxes for $5.89. Another store sells smaller 500 g boxes for $3.19. Problem: How much can you save if you buy the 1.5 kg box? Solution: Step 1: Divide to compare quantities. 1500 ÷ 500 = 3 3 - 500 gram boxes makes a 1.5 kg box. Step 2: Multiply to find the cost of 3 - 500 grams boxes of macaroni $3.19 x 3 = $9.57 Three 500 g boxes cost $9.57 Step 3: Subtract to find the savings $9.57 - $5.89 = $3.68 You can save $3.68 if you buy the 1.5 kilogram box of macaroni. Example 2: The local grocery store sells small and large cans of tomatoes: 1kg (1000 grams) for $3.89 or 500 grams for $2.89. Problem: How much can you save if you buy the 1kg can of tomatoes? Solution: Step 1: Divide to compare quantities. 1000 ÷ 500 = 2 Step 2: Multiply to find the cost of 2 smaller cans of tomatoes 2 x $2.89 = $5.78 Step 3: Subtract to find the savings $5.78 - $3.89 = $1.89 You can save $1.89 if you buy the 1 kg can of tomatoes. 25 Kitchen Math Workbook 25
