Fractions

the number of parts the shape is divided into is called the denominator and is the bottom number of the fraction.

Equivalent fractions and cancelling

a base fractions is one that is written in its simplest terms.

a fraction is in its simplest term if there is no number that is a factor of both the numerator and the denominator.

Equivalent fractions can be found by multiplying both the numerator and the denominator by the same number.

Equivalent fractions can be reduced to a base fraction by cancelling.

to cancel a fraction, look for the highest common factor of the numerator and the denominator.

top heavy fractions and mixed numbers

A top-heavy fractions is a fraction in which the numerator is bigger than the denominator

top heavy fractions are also knowm as improper fractions.

fractions that are not top-heavy are called proper fractions

a mixed fraction is a mixture of a whole number and a proper ftraction

h

to change a top heavy fractions into a mixed numnber, divide the numerator by the denominator to find the whole number, then the remainder is the number of the proper fractions

to change a mixed number into a top-heavy fractions, multiply the whole number by the denominator and add the result to the numerator, to find the numerator od the top-heavy fractions.
