Real-World Examples
Case Study 1: Baking
If a recipe calls for 1/4 cup of sugar and you want to make 1.5 times the recipe, you would calculate 1.5 * (1/4) = 0.375 or 3/8 cups of sugar.
Case Study 2: Finance
If you have a loan with a 6% interest rate and you want to know the interest for a $10,000 loan, you would calculate 0.06 * $10,000 = $600 in interest.
Case Study 3: Engineering
If a structure can withstand a load of 1000 kg and you want to know the load it can withstand at 75% capacity, you would calculate 0.75 * 1000 kg = 750 kg.
