<<2/”>a href=”https://exam.pscnotes.com/5653-2/”>p>Understanding decimal numbers and their representations in various forms is crucial for mathematical Literacy. This includes the ability to convert between forms such as tens, tenths, and hundredths. In this discussion, we will examine the key differences between the numbers represented as 4 tens 12 tenths and 25 hundredths versus 3 tens 14 tenths, explore their advantages and disadvantages, highlight their similarities, and address some frequently asked questions about these representations.

Criteria 4 Tens 12 Tenths and 25 Hundredths 3 Tens 14 Tenths
Standard Form 40 + 1.2 + 0.25 = 41.45 30 + 1.4 = 31.4
Expanded Form 40 + 1 + 0.2 + 0.25 30 + 1 + 0.4
Decimal Form 41.45 31.4
Number of Tens 4 3
Number of Tenths 12 (1.2) 14 (1.4)
Number of Hundredths 25 (0.25) 0 (implicit in tenths)
Value Comparison Greater than 3 tens 14 tenths by 10.05 units Less than 4 tens 12 tenths and 25 hundredths by 10.05 units

Advantages:
Clarity in Representation: Breaking down into tens, tenths, and hundredths provides clear understanding of the place value.
Higher Value: The combination results in a higher overall value, which can be advantageous in certain contexts such as financial calculations.
Detailed Breakdown: The inclusion of hundredths allows for more precise representation and calculations.

Disadvantages:
Complexity: The representation can be seen as more complex due to the inclusion of multiple decimal places.
Conversion Effort: Requires more effort to convert into a single standard decimal form.

Advantages:
Simplicity: Easier to understand and convert to standard form as it involves fewer components.
Less Detailed: Easier to work with in basic calculations due to fewer decimal places.

Disadvantages:
Lower Precision: Does not include hundredths, leading to less precise representation.
Lower Value: Overall value is lower compared to 4 tens 12 tenths and 25 hundredths.

A1: To convert 4 tens 12 tenths and 25 hundredths to a decimal, you sum the parts: 40 (tens) + 1.2 (tenths) + 0.25 (hundredths) = 41.45.

A2: To convert 3 tens 14 tenths to a decimal, you sum the parts: 30 (tens) + 1.4 (tenths) = 31.4.

A3: 4 tens 12 tenths and 25 hundredths is more precise due to the inclusion of hundredths.

A4: Hundredths provide a finer level of detail, allowing for more precise measurements and calculations.

A5: Yes, both can be used interchangeably depending on the context and required precision, but they represent different values.

A6: Practical applications include financial calculations, scientific measurements, and any scenario requiring precise numerical representation.
