Decimal Number Conversions

Understanding Decimal Points and Trailing Decimal Places

Decimal Points Explained

A decimal point is the dot in a decimal number that separates the integer part from the fractional part of repeating decimal part. For example, in the number 12.345, the decimal point is after 12, indicating that '345' is the fractional part.

Trailing Decimal Places

Trailing decimal places are the three digits, that follow the decimal point, crucial for determining the precision of a number. In 12.345, '345' are the trailing decimal places.

The World of Fractions and Mixed Numbers

Understanding Fractions

A fraction is made up of two parts: a numerator (top number) and a denominator (bottom number). For example, in calculating the fraction 2332​, 2 is the numerator, and 3 is the denominator.

Mixed Numbers and Remaining Fractions

A mixed number combines a whole number with a fraction, representing integers with values greater than one. For instance, 212221​ is a mixed number, where 2 is the integer, and 1221​ is the remaining fraction.

Converting Decimals to Fractions: Detailed Examples

Converting a Simple Decimal

Let's convert 0.75 to a fraction:

  1. Convert to Fraction: Start by writing 0.75 as a fraction, which is 0.75110.75​.
  2. Multiply to Remove Decimal: Multiply both the numerator and the denominator by 100 to remove the decimal point, resulting in 0.75×1001×100=751001×1000.75×100​=10075​.
  3. Simplify: Simplify the fraction 7510010075​ to 3443​.

Converting a Decimal Fraction with Significant Figures

Convert 0.005 (with 3 significant figures):

  1. Write as Fraction: Represent 0.005 as a fraction, which is 0.005110.005​.
  2. Multiply to Remove Decimal: Multiply both the numerator and the denominator by 1000, resulting in 0.005×10001×1000=510001×10000.005×1000​=10005​.
  3. Simplify: Simplify the fraction 5100010005​ to 12002001​.

Advanced Techniques: Dividing Fractions and Simplifying Results

Dividing Fractions

Understand how to divide fractions by multiplying with the reciprocal. For example, to divide 1441​ by 1221​, calculate 14×21=2441​×12​=42​, which simplifies to 1221​.

Converting and Simplifying Complex Decimals

Let's convert a decimal, and simplify 2.666...

Represent as Fraction:

  • Write the decimal 2.666... as a fraction.
  • Let's call this fraction 'x'. So, we start with x = 2.666...

Multiply to Remove Repeating Decimal:

  • Multiply both sides of the equation by 10.
  • Now the equation looks like: 10x = 26.666...

Subtract to Solve:

  • Subtract the original equation (x = 2.666...) from the new equation (10x = 26.666...).
  • This gives us: 9x = 24 (because 10x - x = 9x and 26.666... - 2.666... = 24).
  • Now, solve for x: x = 24 / 9.


  • Simplify the fraction 24 / 9 to its simplest form.
  • The simplest form is 2 and 2/3 (since 24 divided by 9 is 2 with a remainder of 6, and 6/9 simplifies to 2/3).

Utilizing Conversion Tables and Calculators

Frequently Asked Questions

How does the Decimal to Fraction Calculator handle dividing fractions?
The calculator simplifies dividing fractions by multiplying the dividend (the first fraction) by the reciprocal of the divisor ratio (the second fraction). For example, to divide 1441​ by 1221​, it calculates 14×2=1241​×2=21​.

Can the calculator assist in converting fractions to decimals?
Yes, it can convert fractions of digits into decimals. It divides the numerator by the denominator to produce the decimal equivalent.

What's the process to divide fractions using the calculator?
Input both fractions into the calculator. It multiplies the first fraction by the reciprocal value of the second and provides the simplified result.

How does the calculator determine the greatest common factor (GCF) when simplifying fractions?
The calculator finds the greatest common factor of the numerator and denominator to simplify fractions, ensuring the fraction is reduced to its simplest form.

Is it possible to multiply fractions using the calculator?
Yes, the calculator can multiply fractions. It multiplies fraction by dividing the numerators together and the denominators together, then simplifies the result if necessary.

Can the calculator provide examples for better understanding?
While the calculator doesn’t provide examples, many online resources and the calculator’s accompanying guide offer examples for various decimal and fraction conversions.

How does the calculator help with subtracting one fraction from another?
