Note: This is an introductory section for beginners or intermediates with the exception of the final cross multiplication section.
A fraction is one number divided by another number. It
is the represents an unsolved division, such as 3/5.
- The numerator is the top number that represents the number of parts that are selected.
- The bottom number is the denominator. The denominator represents the number of equal parts into which an entity has been divided.
For example, if a garden is divided into 5 equal plots, 3 of the plots is 3/5 of the garden.
- A fraction that has 0 as its denominator (e.g., 5/0) is infinitely large and undefined (not a real number or integer).
- If the numerator is zero, then the fraction equals zero (e.g. 0/5 = 0).
- If the fraction has a numerator equal to the denominator (e.g., 5/5), the fraction is equal to 1.
Mixed Numbers are numbers that are equal to an integer plus a fraction.
The number 4 2/3 is the integer 4, plus the fraction 2/3. Any mixed number can be written as a fraction, and any fraction greater than 1 can be written as a mixed number.
- To express 4 2/3 as a fraction:
1)
multiply 4 × 3
2)
add the numerator to this product, 12 + 2 = 14
3)
divide by the denominator: 4 2/3 = 14/3.
