Explanation
Problem Analysis We need to calculate the results of the following multiplication problems: a) 39 × 0.04 b) 74 × 0.02 c) 124 × 0.003
Calculations Let's calculate each of these: a) 39 × 0.04 = 1.56 b) 74 × 0.02 = 1.48 c) 124 × 0.003 = 0.372
Final Answer Therefore, the answers are: a) 1.56 b) 1.48 c) 0.372
Examples
Understanding decimal multiplication is crucial in everyday scenarios, such as calculating discounts while shopping. For instance, if an item costs $39 and is 4% off, you would calculate $39 \times 0.04 = $1.56 to find the discount amount. Similarly, calculating tips (e.g., 2% of a $74 bill) or understanding very small percentages (e.g., 0.3% of $124) relies on these basic multiplication skills. Mastering these calculations helps in making informed financial decisions and understanding proportional relationships.
The calculations for the problems are as follows: 39 × 0.04 = 1.56 , 74 × 0.02 = 1.48 , and 124 × 0.003 = 0.372 . The final answers are 1.56 , 1.48 , and 0.372 respectively.
