Fractions and Decimals

8

For people who are not good in mathematics, it is advisable that uses fractions instead of decimals. Fractions make people understand easily compared to decimals. Fractions, decimals, and percentages are almost the same as they represent the same idea. They are methods of representing the parts of a whole or part of an object or something. One must learn them all as different situations lead to their use and therefore one should be proficient in the two conversions.

Fractions are considered to be the most simple and accurate. This is because they are not subject to be rounded off, rounded up or truncation as it is done to fraction to decimal which are often required to a specific number of decimal places or significant figures. They also give a clear picture of the whole. For instance, when comparing two fractions of one whole thing, the one whose numerator is bigger represents the largest portion. Fractions can, therefore, be used in different instances due to the reason that there are easy to multiply and divide them as opposed to decimals.  Fractions can be used in communication with parts instead of doing the long the division methods. For example, sixteen divides by twenty-four can be written as a fraction like 2/3. This takes little time compared to the traditional division methods. Fractions also are not repeating and represent whole numbers.

Where it becomes difficult to compare two fractions, then the need for decimals arises. Alternatively, you can convert them to percentages. When the fractions are not of the same denominator, it’s highly applicable for decimals be used. This is because they give a simple logic of identifying which one is larger than the other. It follows the order of numbers on the number line. If the decimal to fraction starts with zero before the decimal point and another one with one or two then it’s bigger than the first one. For instance, 0.34 is smaller than 3.15.

Care should be taken when converting fractions to decimals or the other way round. This is because one can easily interchange the division. Normally for the improper fraction, it will give a decimal that starts with a number greater than one before putting the decimal point. For a proper fraction, the decimal will be in the form that the number before the decimal point is automatically zero. Decimal points can be repetitive and very long and therefore must be given a condition to a certain number of digits. However, the conversions from decimal to fractions and vice versa is a very simple and quick process.
