Converting a rational number to a decimal using long division. For example if you have a rational number of 2/5 you would set up the equation as 2 divided by 5 which requires long division. The answer to this would then be the decimal number 0.4.

If its a rational number then its decimal equivalent can be expressed as a fraction

You undertake a long division. Any fraction is a rational number and so its decimal representation must be terminating or recurring. A terminating decimal will mean that the long division reaches a point when the remainder is zero. A recurring decimal sequence is equivalent to the long division going through a cycle of remainders.
