Proper and Improper Fractions
A proper fraction has a numerator smaller than its denominator (value less than 1), whereas an improper fraction has a larger numerator (value greater than or equal to 1).
Mixed Fractions
A mixed fraction consists of a whole number combined with a proper fraction, such as 2 1/3, and can always be converted into an improper fraction.
Multiplication of Fractions
To multiply two fractions, simply multiply their numerators together to get the new numerator, and their denominators together to get the new denominator.
Division of Fractions
To divide a fraction by another fraction, multiply the first fraction by the reciprocal (flipped version) of the second fraction.
Multiplication of Decimals
When multiplying decimals, multiply the numbers as whole numbers first, then place the decimal point in the product by counting total decimal places from both factors.

Frequently Asked Questions
Why do we need to find the LCM when adding fractions?
We find the Least Common Multiple (LCM) of the denominators to convert unlike fractions into like fractions so that their numerators can be directly added or subtracted.
How do I know where to place the decimal point when multiplying decimals?
Count the total number of decimal places in all the numbers you are multiplying, and place the decimal point in your answer so it has that same total number of decimal places from the right.
What is the easiest way to remember fraction division?
Use the phrase 'Keep-Change-Flip': Keep the first fraction the same, change the division sign to multiplication, and flip the second fraction into its reciprocal.
