Chapter 7: Problem 101

Explain the difference between \(25 \%\) and \(0.25 \%\)

Short Answer

Expert verified
25% (0.25) is larger than 0.25% (0.0025).

Step by step solution

01

- Understand the Percentages

First, recall that a percentage is a way of expressing a number as a fraction of 100. For example, 25% means 25 out of 100, and 0.25% means 0.25 out of 100.
02

- Convert Percentages to Decimal Form

Convert the percentages to decimal form by dividing by 100. For 25%, calculate \(25 \div 100 = 0.25\). For 0.25%, calculate \(0.25 \div 100 = 0.0025\).
03

- Compare the Decimal Values

Now compare the decimal values. 25% converted to a decimal is 0.25, while 0.25% converted to a decimal is 0.0025. Clearly, 0.25 is much larger than 0.0025.

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

percentage conversion
When working with percentages, remember that they are a way of expressing numbers as parts of a whole. This whole is always 100. To convert a percentage to a decimal, divide the percentage by 100. This step is crucial as it helps in performing arithmetic operations and comparing different values. For example, let's convert 25% and 0.25% to their decimal forms. For 25%, we have: 25 梅 100 = 0.25.
For 0.25%, we have: 0.25 梅 100 = 0.0025.
This conversion simplifies manipulation and comparison of percentages.
decimal form
Understanding decimal form is essential in mathematics. A decimal number is a way of representing fractions based on the powers of 10. To grasp decimal form, think of it as a number divided into tenths, hundredths, thousandths, etc. For percentages, converting to decimal form means simplifying them for easy comparison. Recall:
  • 25% converted to decimal is 0.25

  • 0.25% converted to decimal is 0.0025
This method breaks down the percentage into smaller, easily comparable numbers. Paying close attention to decimal places can help understand and distinguish between numbers like 0.25 and 0.0025, where one is significantly smaller than the other.
comparing decimals
Once percentages have been converted to decimal form, comparing them becomes straightforward. You can visually compare and determine which one is larger or smaller. For example, let鈥檚 compare 0.25 and 0.0025. The value of 0.25 is much larger than 0.0025 because the position of the digits is far more to the left in the number line.
This position indicates higher value. Comparing decimals:
  • 0.25 (has two decimal places)

  • 0.0025 (has four decimal places)
Clearly, 0.25 is closer to 1 than 0.0025. This clarity in comparison aids in understanding the significant difference in their values post conversion.
