Decimals and Fractions

When it comes to numbers, decimals and fractions are both commonly used representations. Understanding the relationship between decimal numbers and fractions is essential for various mathematical operations and real-life applications. Let’s explore the concept of decimals and how they can be expressed as fractions.

A decimal number is a number that contains a decimal point, which separates the whole number part from the fractional part. The decimal point is typically represented as a dot “.”. For example, 0.5, 0.25, and 0.75 are all decimal numbers.

Decimals can also be written as fractions, with the decimal part serving as the numerator and the denominator being powers of 10. For example, 0.5 can be expressed as the fraction 1/2, 0.25 as 1/4, and 0.75 as 3/4.

Example:

To convert 0.5 to a fraction, you can write it as 1/2. The decimal point separates the whole number part (0) and the fractional part (5). Since 5 is in the tenths place, it becomes the numerator, and the denominator is 10 (one zero for each decimal place). Therefore, 0.5 is equivalent to 1/2.

To convert a decimal to a fraction, you can use the place value system and express the decimal part in terms of tenths, hundredths, thousandths, and so on. For example, 0.25 can be expressed as 25 hundredths, which simplifies to 1/4.

By understanding how decimals and fractions are related, you can easily convert decimal numbers to fractions and vice versa, making math calculations and comparisons more accessible.

Summary:

  • Decimals are numbers that have a decimal point, separating the whole number part from the fractional part.
  • Decimals can be expressed as fractions with denominators as powers of 10.
  • Example: 0.5 can be written as 1/2, 0.25 as 1/4, and so on.

Remember, understanding the relationship between decimals and fractions can simplify mathematical calculations and provide a clearer understanding of numeric values.

Terminating Decimals:

Terminating decimals are decimal numbers that have a finite number of digits after the decimal point. To convert a terminating decimal to a fraction, follow these steps:

  1. Write the decimal as the numerator of the fraction.
  2. Write 1 followed by as many zeroes as the number of digits after the decimal point as the denominator of the fraction.
  3. Simplify the fraction if possible.

For example, let’s convert 0.25 into a fraction:

0.25 = 25/100

Repeating Decimals:

Repeating decimals are decimal numbers that have a pattern of one or more digits repeating infinitely. To convert a repeating decimal to a fraction, follow these steps:

  1. Let x be the repeating decimal.
  2. Multiply x by 10 raised to the power of the number of digits in the repeating pattern.
  3. Subtract x from the previous step from the original x.
  4. Write the obtained value as the numerator of the fraction.
  5. Write 9 followed by as many zeroes as the number of digits in the repeating pattern as the denominator of the fraction.
  6. Simplify the fraction if possible.

For example, let’s convert 0.333… into a fraction:

x = 0.333…
10x = 3.333…
10x – x = 3.333… – 0.333…
9x = 3
x = 1/3
