Identify Weights: Step 1: Identify the weights of the textbooks and set up the subtraction problem.Kirk's chemistry textbook weighs 43 pounds and his geometry textbook weighs 21 pounds. To find out how much more the chemistry textbook weighs, subtract the weight of the geometry textbook from the weight of the chemistry textbook.Calculation: 43−21
Find Common Denominator: Step 2: Find a common denominator for the fractions.The common denominator for 4 and 2 is 4. Convert 21 to 42 so both fractions have the same denominator.Calculation: 21=42
Perform Subtraction: Step 3: Perform the subtraction with the common denominator.Now subtract the two fractions: 43−42Calculation: (43−2)=41
