What are Fractions?
One way to think of a fraction is as a portion of a whole number. There are two parts to a fraction: the numerator and the denominator. Fractions are a useful mathematical form that may be applied to many tasks. Based on the comparison between single fractions and multiple fractions, they are of five types:
Type | Description | Example |
Proper Fractions | Numerator < Denominator; Value < 1 after simplification | 3/5, 2/3, 9/11 |
Improper Fractions | Numerator > Denominator; Value >= 1 after simplification | 5/2, 9/5, 10/6 |
Mixed Fractions | Combination of whole numbers and fractions; Can be converted to proper fractions | 2 ⅓, 3 ⅓ |
Like Fractions | Fractions with the same denominator | 1/2, 3/2, 5/2, 2/2 |
Unlike Fractions | Fractions with different denominators; More complex to simplify | 1/2, 1/3, 1/4, 1/5 |

What are Decimals?
In arithmetic Math, decimal numbers can be characterized as numbers with a whole number part and a fractional part separated by a decimal point. Below we have mentioned the types of decimals:
Types | Description | Example |
Recurring (Repeating or Non-Terminating) | Digits after the decimal point repeat infinitely. | 3.125125 (finite)3.1212121212… (infinite) |
Non-Recurring (Non-Repeating or Terminating) | Digits after the decimal point do not repeat. | 3.2376 (finite), 3.137654… (infinite) |
Decimal Fraction | Represents a fraction with a denominator in powers of 10. | 81.75 = 8175/100 |

Difference between Fractions and Decimals Questions
Fractions and decimals are interconnected yet are different from each other. One of the major differences between the two is that fractions are simple expressions of ratios of whole numbers. They are not divided by decimals. On the other hand, decimals represent infinite numbers such as the value of pi. Read the below table to get a better understanding:
Aspect | Fractions | Decimals |
Representation | p/q (where q ≠ 0) | Whole number part is connected to the fractional part via a decimal point |
The type of numbers represented | Ratios of whole numbers | Can represent both finite and infinite numbers, such as the value of pi |
Division by decimals | Not applicable | Possible, as decimals involve division |
Common examples | 1/2, 3/4, 5/6 | 0.5, 0.75, 0.333… (repeating) |
Conversion between the two | Convert to decimal: Divide the numerator by the denominator.Ex-Convert 8/10 to decimal; 8/10 = 0.8 | Convert to fraction: Write the decimal as a fraction, simplify if possible.Ex-Express 1.25 as a fraction;1.25 = 125 x (1/100) = 125/100 = 5/4 |

A decimal fraction is a fraction whose denominator is a power of 10. For example, 0.5, 0.75, and 0.125 are decimal fractions.
To solve decimal fraction problems, you can use operations like addition, subtraction, multiplication, and division, similar to whole numbers, but maintaining decimal point alignment.
To convert a fraction to a decimal, divide the numerator by the denominator. For example, 3/4 becomes 0.75 when divided.
Examples of decimals to fractions conversion are:0.5 becomes ½,0.75 becomes 3/4, and 0.125 becomes ⅛, etc.
