Welcome to the Math Salamanders Learning Fractions support page.
Here you will find information and support about everything to do with fractions.
We have a huge range of resources, from fraction calculators and fraction conversion sheets to fraction information posters, fraction strips and flashcards.
Fractions is an area that a lot of kids find hard to understand. One of the problems with fractions is that they have different meanings depending on the context.
For example, you can eat half an apple or cut an orange into fourths. But you can also put the number one-half on a number line, measure a line 3 1/2 cm long, or find a fourth of 24.
Once the concept of fractions as numbers and fractions as parts of a whole has been understood, your child will be well on their way to developing a sound understanding of fractions.

A fraction is a number which contains parts of a whole.
Fractions can be smaller than or larger than one (one whole).
A fraction is a number with the form: \[ {n \over d} \]
where n and d are two numbers.
Alternative ways of expressing this statement include:
n over d, n/d, n ÷ d
The fraction \[ {5 \over 6} \] could be expressed as:
A fraction is a number with the form: \[ {n \over d} \]
Please note: the comparisons between the numerator and denominator above assume that they are both positive numbers. If either n or d is negative, then we need to compare their absolute values to find outwhether the fraction is a proper fraction or an improper fraction
\[{3 \over 7} \; , \; {2 \over 10} \; , \; -{3 \over 5} \; and \; {17 \over 26} \] are all proper fractions.
\[ {31 \over 5} \; , \; {15 \over 10} \; , \; -{17 \over 3} \; and \; {37 \over 23} \] are all improper fractions.
\[ 3{1 \over 5} \; , \; 2 {5 \over 8} \; and \; 4 {1 \over 2} \] are all mixed numbers or mixed fractions.

A common or vulgar fraction is simply an ordinary fraction.
The numerator and denominator must be integers, or whole numbers, and the denominator cannot equal zero.
\[ {35 \over 45} \; , \; {5 \over 9} \; and \; {51 \over 16} \] are all common or vulgar fractions.
\[ {3.2 \over 4.5} \; , \; {5 \over 0} \; and \; {0.57 \over 1.6} \] are NOT common or vulgar fractions.
A decimal fraction is a fraction where the denominator is a power of ten.
\[{7 \over 10} \; , \; {5 \over 100} \; , \; {537 \over 1000} \]
are all decimal fractions.
They are equal to 0.7, 0.05 and 0.537 respectively.
\[{3 \over 5} \; , \; {2 \over 12} \; and \; {263 \over 500} \] are not decimal fractions.
Here are the formulas for adding, subtracting, multiplying and dividing two fractions:
Formula for adding two fractions
\[{a \over b} + {c \over d} = {ad + bc \over bd} \]
Formula for subtracting two fractions
\[{a \over b} - {c \over d} = {ad - bc \over bd} \]
Formula for multiplying two fractions
\[{a \over b} \times {c \over d} = {ac \over bd} \]
Formula for dividing two fractions
\[{a \over b} \div {c \over d} = {ad \over bc} \]

To convert a fraction to a percentage follows on simply from converting a fraction to a decimal.
Simply divide the numerator by the denominator to give you the decimal form. Then multiply the result by 100 to change the decimal into a percentage.

Often when we are talking about and using fractions, we are looking at fractions of numbers or quantities.
To find a fraction of a number or quantity, we need to first divide the number or quantity by the denominator. Then multiply this by the numerator to give the answer.
