**Decimal Expansion of Rational Number with solved examples**

First, rational numbers may have a repeating decimal, like 1/6 = 0.16666... etcetera, so they do not necessarily have a finite expression when written in decimal form. The definition of 'even' and 'odd' makes most sense in the context of exponentiation. If we have an even exponent, then we have two roots (real or imaginary). If we have an uneven exponent, then we have only one.... 108 Responses to GMAT Math: Terminating and Repeating Decimals Ellie November 9, 2018 at 4:41 pm # What is 2/9, 3/9, 4/9, 5/9, 6/9, 7/9, 8/9 as a decimal please tell me is it …

**Why are Non-terminating Repeating Decimals Rational**

The number of digits in the repeating portion of the decimal expansion of a rational number can also be found directly from the multiplicative order of its denominator. My number theory is a bit rusty at the moment, so the best I can do is point you in that direction.... if the denominator is a prime number other than a 2 or a 5, or if the prime factorization of the denominator contains any prime numbers other than 2's or 5's, the decimal expansion of the fraction will be repeating

**How do I tell if a fraction is rational or irrational**

Another clue is that the decimal goes on forever without repeating. Cannot Be Written as a Fraction. It is irrational because it cannot be written as a ratio (or fraction), not because it is crazy! So we can tell if it is Rational or Irrational by trying to write the number as a simple fraction. Example: 9.5 can be written as a simple fraction like this: 9.5 = 192. So it is a rational number how to make your blue eyes stand out www.ck12.orgConcept 1. Rational Numbers Take a few minutes to check your work with a partner. Write down the de?nition of a rational number and how you can tell if a number is rational or not.

**What is a Terminating Decimal? Virtual Nerd**

decimal representation of a rational number is obtained by dividing the numerator of a fraction by the denominator. This lesson would be preceded by a lesson that teaches the concept of rational numbers that uses examples and non-examples to determine what is meant by a rational number. This lesson will span more than one class period. Prerequisites: knowledge of prime numbers, how to how to tell if a girl likes me Moving on, to decimal expansion of rational numbers which are recurring, the following theorem can be stated: Theorem 3: If m is a rational number, which can be represented as the ratio of two integers i.e. \(\frac{p}{q}\) and the prime factorization of q does not takes the form \(2^x~ 5^y\) , where x and y are non-negative integers.

## How To Tell If A Decimal Is Rational

6/02/1998 · When this happens, we know the original assumption must have been false; in this case, we know that the square root of 10 is irrational. (We haven't done this yet! I'm just telling you the strategy we're going to use). So suppose the square root of 10 is a rational number. Then it must be of the form a/b, where a and b are whole numbers. Furthermore, we can assume that a and b don't have any
