Fraction Calculator
A fraction calculator that helps you perform various mathematical operations including addition, subtraction, multiplication, and division of fractions.
Fraction Syntax
A fraction is a way of representing a part of a whole. The standard syntax for writing a fraction is:
- Numerator: The number above the line, representing the number of parts.
- Denominator: The number below the line, representing the total number of equal parts.
Types of Fraction Notation
There are three types of fraction notation:
1. Proper Fraction
A proper fraction is a fraction where the numerator is less than the denominator. It represents a part of a whole that is less than one (e.g. 2/5).
2. Improper Fraction
An improper fraction is a fraction where the numerator is greater than or equal to the denominator. It represents a part of a whole that is equal to or greater than one (e.g. 5/2).
3. Mixed Number
A mixed number is a number that consists of a whole number and a proper fraction. It represents a part of a whole that is greater than one (e.g. 2 1/2).
Real Life Examples of Fractions
Finance
In real-time, finance uses fractions in budgeting to instantly calculate what portion of your income goes to a specific expense category (e.g. a quarter of my salary for rent) or to quickly determine your exact share when splitting shared household bills.
Construction and DIY
Real-time fraction use here means instantly adding or subtracting fractional measurements for materials to ensure precise cuts and fits.
Time Management
This involves instantly understanding and calculating fractional periods of time, like knowing how long "a quarter of an hour" is or how much of your workday is "three-quarters done."
Sports Statistics
In sports, real-time fraction applications involve immediately understanding player performance metrics, such as a "two-thirds" completion rate for a quarterback, to assess ongoing game situations.
Addition of Fractions
The general way to write the addition of two fractions is:
a and c are the numerators (the top numbers).
b and d are the denominators (the bottom numbers).
The + symbol indicates addition.
Example
You earn $2000 per month. You decide to spend 1/2 (one-half) of your income on rent and 1/4 (one-fourth) on groceries. What total fraction of your income have you planned for these two expenses, and how much money is that?
The total fraction of your income allocated to rent and groceries is 3/4 (three-fourths). This amounts to $1,500.
Calculation:
- Calculate individual dollar amounts:
- Rent cost: $2000 × 1/2 = $1000
- Groceries cost: $2000 × 1/4 = $500
- Add the fractions for total allocation:
- To add 1/2 + 1/4, find a common denominator, which is 4
- Convert 1/2 to 2/4 (by multiplying both numerator and denominator by 2)
- Add the numerators: 2/4 (Rent) + 1/4 (Groceries) = 3/4 (Total allocation)
- Add the dollar amounts for total cost:
- $1000 (Rent) + $500 (Groceries) = $1500 (Total cost)
