Math Problem Statement

Division of whole numbers with decimals to decimal then may have division of whole numbers with decimal to whole numbers with decimals Give me an example and explanation for my reporting

Solution

Here’s a clear example and explanation to include in your reporting about division of whole numbers with decimals:


Example 1: Dividing a Whole Number by a Decimal to Get a Decimal Result

Problem:

Divide 24÷0.624 \div 0.6.

Step-by-Step Explanation:

  1. Rewrite the Problem to Eliminate the Decimal in the Divisor: Multiply both the dividend (24) and the divisor (0.6) by 10. This simplifies the division by turning the divisor into a whole number: (24÷0.6)=(240÷6)(24 \div 0.6) = (240 \div 6)

  2. Perform the Division: Divide 240240 by 66: 240÷6=40240 \div 6 = 40

  3. Interpret the Result: The quotient is 4040. Thus: 24÷0.6=4024 \div 0.6 = 40


Example 2: Dividing a Whole Number by a Decimal to Get a Whole Number and Decimal Result

Problem:

Divide 35÷1.235 \div 1.2.

Step-by-Step Explanation:

  1. Rewrite the Problem to Eliminate the Decimal in the Divisor: Multiply both the dividend (35) and the divisor (1.2) by 10. This simplifies the division: (35÷1.2)=(350÷12)(35 \div 1.2) = (350 \div 12)

  2. Perform the Division: Divide 350350 by 1212. Perform the long division:

    • 350÷12=29.1667350 \div 12 = 29.1667 (approximately).
  3. Interpret the Result: The quotient is approximately 29.1729.17. Thus: 35÷1.229.1735 \div 1.2 \approx 29.17


Tips for Reporting

  1. Always clarify how decimals in the divisor are removed for simplicity.
  2. Show the multiplication factor used to eliminate the decimals.
  3. Use long division when necessary for detailed explanation.
  4. Clearly round answers to the required decimal places if the result is not exact.
  5. Provide visual aids, like charts or tables, for step-by-step guidance in calculations.

Do you want me to format these examples further or provide visual explanations?

Here are some relative expansion questions:

  1. What is the importance of removing decimals from the divisor in division problems?
  2. How can this approach be applied to mixed decimals in both dividend and divisor?
  3. Are there other methods to simplify division with decimals apart from multiplication?
  4. How can this method be adjusted for large or very small numbers?
  5. What strategies can be used to check the accuracy of the quotient?

Tip: Always double-check the position of the decimal point when multiplying or dividing by powers of 10 to avoid errors.
