Relationship Between Fractions and Decimal

Relationship Between Fractions and Decimal: Let us imagine fractions and decimals as two best friends, Fraction and Decimal lived in a small town, settled in the middle of the rolling hills. In his official manner, Fraction always insisted that things were to be divided into equal parts while decimals were simply smooth and flexible. However, in their friendship, there was a unique harmony. Their friendship is just the same as the relationship between fractions and decimals in the world of mathematics. So, buckle up! In this article, you will understand the unique and most important relationship between fractions and decimals.

Relationship Between Fractions and Decimal

Fractions:

A fraction simply personifies a portion of a whole. It is expressed as a numerator (the top number) divided by a denominator (the bottom number).

Let us take an example,

1/2 denotes one out of two equally divided parts of a whole.

Imagine a rectangular board being divided into two pieces. In this scenario, 1/2 would correspond to one of those pieces.

Decimals:

Decimals utilize a decimal point to distinguish the whole number from its fractional component.

Take 0.5, for instance. In this case, the “0” signifies no complete units, while the “5” following the decimal point represents five-tenths (5/10), which is the same as 1/2.

Importance of fractions and decimals:

Fractions:

  • Fractions are used for precise measurement and they ensure accuracy in recipes, carpentry, sewing, and also in scientific measurements.
  • Fractions are better options when you want to share fairly which means dividing resources such as food between two can be divided as ½, fabric and time, etc which is possible with fractions.
  • Fractions help in visualizing parts which help us in comprehending the portions and ratios.
  • Fractions also help us understand mathematical concepts such as probability.
  • Fractions are the basic part that helps one to have a good knowledge of finance, it helps you to understand concepts like interest, investing, and managing which are crucial for managing finance and budget effectively.
  • Fractions improve problem-solving quality by increasing logical thinking and analytical skills to operate with fractions in different mathematical atmospheres.

Decimals:

  • Decimals help in mathematical calculations to calculate them efficiently, mainly dealing with money, and measuring higher precisions.
  • Decimals help you represent small quantities or small amounts like scientific measurements or in money transactions etc.
  • Decimals are more compact than a fractions in some cases.
  • They are used in data analysis and interpretation of data.

Limitations of fractions and decimals:

Fractions:

  • It is very difficult for us to perform complex calculations using fractions and it is a very time-consuming process.
  • It is not possible for us to represent very small or very large values using fractions and can become unhandy.
  • Comparison of fractions with different denominators can be visually difficult.
  • For certain calculations fractions need to be converted to decimals sometimes.
  • Fractions are unlikely less popular which means they are not used in everyday life.

decimals:

  • With decimals it becomes difficult to represent certain fractions exactly sometimes and may lead to rounding errors.
  • Sometimes it is difficult for beginners to understand the concepts of decimals.
  • Decimals also have same limitation as fractions, they also require conversion from decimals to fractions for certain calculations.
  • If you represent fractions with decimals sometimes it can lead to repetition of patterns.
  • There are chances of getting significant errors in calculations if you misplace the decimal point.

Relationship between fractions and decimals:

(Fun fact: fractions and decimals are the two sides of the same coin.)

Here is how both are connected

  1. Converting fractions to decimal:

Divide the numerator by denominator then you will get a decimal number.

Here is an example:

Let us take a number 3/5 when you divide it you will get 0.6

3/5 à fraction part

0.6 à decimal part

   2. Converting decimals to fractions:

First, write the decimal as a fraction with the digit after the decimal point as the numerator and a denominator of 1 followed by zeros equal to the number of decimal places.

Here is an example:

Let us take the number 0.6 and it becomes 6/10 and further can be simplified to 3/5.

Where 3/5 à fraction part

0.6 à decimal part

Real-time Applications of decimals and fractions:

Here are some real-life examples,

  • Both decimals and fractions are used in financial calculations such as currency conversions, interest, loans stocks, etc.
  • Even fractions and decimals are used in kitchens for cooking and baking in measuring the quantities of food items such as half a cup of water, one-fourth of flour, etc.
  • They can be used in the engineering field for construction work and in manufacturing to measure lengths, height, and width as well as volumes, which are represented either in fractions or in decimals.
  • Decimals and fractions can also be used in statistics to represent percentage value, probability, and data points.
  • They help us analyze trends, patterns, and relations between different datasets and decision-making for research and business.
  • Doctors use fractions and decimals to prescribe and control medicine doses accurately.

Doses can be in milligrams or millimeters precise calculation can be beneficial to patient safety.

  • Global positioning system (GPS) also uses fractions and decimals for mapping and navigation.
  • Latitude and longitude on the world map are represented using decimals to pinpoint the locations accurately.

Ultimately, fractions and decimals are hardly two separate entities but nicely meshed in our world; they can do a lot together. For special measurements, fractions give clarity and exactness. Decimals, on the other hand, excel in calculations and presenting high-precision values. They both find applications in a vast array of fields: baking a perfect cake or constructing a skyscraper for instance. Knowing these facts enables us to select the best tool for any given job that we have to accomplish.

In short, fractions and decimals are mutually exclusive codes within the digits’ domain. By mastering both one can get deeper into this physical aspect of reality including all its beautiful details such as in scientific experiments’ tricky manipulations or even day-to-day measurement activities. It is therefore important that the next time you come across a fraction or decimal number; you should see an opportunity to enter into an exciting world of numerical representation.
