Understanding Decimals

Decimals are a way of representing fractions with a denominator of 10 or a power of 10. They are used to express numbers that have a fractional part, and are often used in everyday life, such as in financial transactions, measurements, and calculations. In this article, we will explore how to arrange decimals in order from smallest to largest.

The Importance of Arranging Decimals

Arranging decimals in order is an essential skill in mathematics, particularly in arithmetic and algebra. It is used in various applications, such as:

Comparing prices and values
Calculating percentages and ratios
Solving equations and inequalities
Analyzing data and statistics

The Correct Order of Decimals

To arrange decimals in order, we need to compare their values. We can do this by looking at the decimal point and the digits that follow it. Here are the steps to follow:

Compare the whole numbers: If the whole numbers are different, the decimal with the smaller whole number comes first.
Compare the decimal parts: If the whole numbers are the same, compare the decimal parts. The decimal with the smaller decimal part comes first.
Compare the digits: If the decimal parts are the same, compare the digits that follow the decimal point. The decimal with the smaller digit comes first.

Arranging the Given Decimals

Now, let's apply these steps to the given decimals: ${ $0.84\$}$ , ${ $0.125\$}$ , ${ $0.9\$}$ , and ${ $0.34\$}$ .

Compare the whole numbers: The whole numbers are different, so we can proceed to the next step.
Compare the decimal parts: The decimal parts are also different, so we can proceed to the next step.
Compare the digits: The digits that follow the decimal point are also different, so we can proceed to the next step.

The Correct Order

After comparing the decimals, we get the following order:

${ $0.125\$}$
${ $0.34\$}$
${ $0.84\$}$
${ $0.9\$}$

Therefore, the correct order is:

${ $0.125, 0.34, 0.84, 0.9\$}$

Conclusion

Arranging decimals in order is a simple yet essential skill in mathematics. By following the steps outlined in this article, you can easily compare and arrange decimals in order from smallest to largest. Remember to compare the whole numbers, decimal parts, and digits that follow the decimal point to get the correct order.

Frequently Asked Questions

Q: How do I compare decimals with different whole numbers?

A: Compare the whole numbers first. The decimal with the smaller whole number comes first.

Q: How do I compare decimals with the same whole number?

A: Compare the decimal parts. The decimal with the smaller decimal part comes first.

Q: How do I compare decimals with the same decimal part?

A: Compare the digits that follow the decimal point. The decimal with the smaller digit comes first.

Q: What if the digits are the same?

A: If the digits are the same, the decimals are equal, and there is no order.

Frequently Asked Questions and Answers

Q: What is a decimal?

A: A decimal is a way of representing a fraction with a denominator of 10 or a power of 10.

Q: How do I compare decimals?

A: To compare decimals, compare the whole numbers first. If the whole numbers are the same, compare the decimal parts. If the decimal parts are the same, compare the digits that follow the decimal point.

Q: How do I add decimals?

A: To add decimals, line up the decimal points and add the digits in each place value. If the sum of the digits in a place value is greater than 9, carry the excess to the next place value.

Q: How do I subtract decimals?

A: To subtract decimals, line up the decimal points and subtract the digits in each place value. If the difference of the digits in a place value is less than 0, borrow from the next place value.

Q: How do I multiply decimals?

A: To multiply decimals, multiply the numbers as if they were whole numbers, and then count the total number of decimal places in the factors. The product will have the same number of decimal places as the total number of decimal places in the factors.

Q: How do I divide decimals?

A: To divide decimals, divide the numbers as if they were whole numbers, and then count the total number of decimal places in the dividend. The quotient will have the same number of decimal places as the total number of decimal places in the dividend.

Q: What is the difference between a decimal and a fraction?

A: A decimal is a way of representing a fraction with a denominator of 10 or a power of 10, while a fraction is a way of representing a part of a whole.

Q: How do I convert a decimal to a fraction?

A: To convert a decimal to a fraction, write the decimal as a fraction with a denominator of 10 or a power of 10, and then simplify the fraction.

Q: How do I convert a fraction to a decimal?

A: To convert a fraction to a decimal, divide the numerator by the denominator.
