repeating decimal
repeating decimal
A repeating decimal or recurring decimal is decimal representation of a number whose digits are periodic (repeating its values at regular intervals) and the infinitely repeated portion is not zero. … The infinitely repeated digit sequence is called the repetend or reptend.

. Students should know the perfect squares (1 to 15) in order to approximate the value of irrational numbers.
How do you approximate irrational numbers?
Estimating Irrational Numbers
- Count up until you hit a square root that works.
- Count down until you hit a square root that works.
- Square root the high and low number, then graph their points on a number line.
- Your estimate should be somewhere between those two numbers. Example:

Why do we calculate an approximate value of an irrational number?
When finding the square root of a number that is not a perfect square, you will often find an answer that is an irrational number. An irrational number is a number that can’t be written as any fraction and will have a decimal that continues forever with no repeating pattern.
How do you approximate a number?
An approximation is anything that is similar, but not exactly equal, to something else. A number can be approximated by rounding. A calculation can be approximated by rounding the values within it before performing the operations .

What is an example of approximate?
The definition of approximate is a time or a tangible item which is close to something else but not exactly like it. Stating that a play will start at 7:00 when it will actually start a few minutes after that is an example of the time of 7:00 being an approximate time.
What are approximation examples?
Not exact, but close enough to be used. Examples: the cord measures 2.91, and you round it to “3”, as that is good enough. the bus ride takes 57 minutes, and you say it is “a one hour bus ride”.

Do all irrational numbers have some repeating pattern?
It is not possible that an irrational number has a repeating pattern, even if it were after trillions or quadrillions of decimal places. An irrational number cannot be represented as a fraction p/q of p,q being integers, if a number has a decimal expansion which eventually repeats, then it cannot be rational, end of.
