How to convert a terminating decimal into a rational number of the form (p over q)  Number theory
Show Description Hide DescriptionIn this video , we have studied the techniques how to convert a terminating decimal expansion into a rational number of the form p/q. In order to covert a terminating decimal into a rational number we, follow the steps (i) Determine the number of digits in decimal part (ii) Remove decimal point from numerator and write 1 in denominator and put as many zeros as on the right side of 1 as the number of digits in the decimal part of the given rational number.

How to convert a terminating decimal into a rational number of the form (p over q)  Number theory


<< Stop >> Please put the topic into your summary form. Stop and think about what we are gong to do.....what does a terminating decimal? What is a rational number look like?

Remember, the definition of a rational number is a number that can be written as a fraction. So a terminating decimal is a rational number....we are just putting it in fractional form.

<< Stop>> You may need to add to your notes some of what he is saying, for instance, you should have written how he knows to add two zeros to the denominator here....by the number of digits in the decimal part of the number.

He is just simplifying the answer.....all answers in mathematics should be simplified fully.

Make sure you are getting all three of these examples into your notes. If you don't understand any part of it please email Mr. Venner.

The number of digits "in the decimal part of the number", that means to the right of the decimal only!!

He just keeps simplifying the fraction by dividing the denominator and numerator by 2.
