Identify well-known fractional equivalents of decimals. Convert obscure decimals and recurring decimals into fractions.

Convert a variety of numbers from decimal to standard index form.

Round numbers to a given number of decimal places.

Represent a given probability to a decimal, fraction or percentage.

Arithmetic operations involving fractions; converting between decimals and fractions; deciding if fractions are equivalent.

Addition and subtraction of integers and decimals.

Manipulate fractions in order to add and subtract them. The difficulty escalates through the inclusion of a whole integer and a decimal, which both need to be converted into a fraction before the addition/subtraction can take place.
