Fractions Recap

 

The top number is called the Numerator and is the number of equal 
parts in the fraction.

The bottom number is called the Denominator and is the total number of 
equal parts in the fraction.

Proper Fraction is when the numerator is smaller than the denominator.

An Improper Fraction is when the numerator is greater than the denominator.

Mixed Number is a mixture of whole numbers and fractions.

If you multiply or divide the numerator and the denominator by the same number,  then the fraction remains the same and is said to be Equivalent.

Remember that with a fraction, whatever we do to the top (numerator), we must do to the bottom (denominator). Simplifying.

Like Fraction has the same denominator (bottom number).

To add like fractions (same denominator) you just add the numerators and keep the denominator the same.

To subtract like fractions (same denominator) you just subtract the numerators and keep the denominator the same.

To multiply fractions all you need to do is to change any mixed numbers
into improper fractions, multiply the numerators, multiply the denominators
and then simplify the result.

To divide fractions, we convert the calculation from a divide to multiplication 
and then treat it as a multiplication.

We can only compare fractions if their denominators are the same. If the denominators are different, we need to make them the same, using our knowledge of equivalent fractions.
