Irrational Numbers

Its the pie formula

Rational

5.121212 = 5 121212/1000000 As a rational fraction .

However, if you mean 5.121212.... (recuring to infinity_

Then

Let P = 5.121212....

&

100P = 512.121212...

Subtract

99P = 507 (Note the recuring decimals subtract to zero)

P = 507/99

P = 5 12/99

P = 5 4/33 Which is also rational .

NB Terminating decimals do NOT have a series of stops.

Recuring to infinity decimals have three or more dots/stops after the last decimal digit.

0.95832758941 is rational. Rational numbers are numbers that can be written as a fraction. Irrational numbers cannot be expressed as a fraction.

Rational because you can coinvert it to a ratio(fraction).

0.6 = 6/10 = 3/5

NB Irrational numbers are those that cannot be converted to a fraction. e,g, pi = 3.1415692.... or sqrt(2) = 1.414213562....

There are many more irrational numbers.

sqrt(4/9) = 2/3 = 0.666...

Which is NOT irrational .

IRRATIONAL

sqrt(15) = sqrt(3 x 5) =sqrt(3) X sqrt(5)

Since the 'square roots' of prime numbers , '3' & '5' in this case, are irrational , then the square root od '15' is irrational .

0.636363... ( recurring to infinity) is a RATIONAL number.

It can be converted to a ratio/fraction.

Let P = 0.636363...

&

100P = 63.636363....

Subtract

99P = 63

P = 63/99 ( A ratio/fraction).

Cancel down by '9'

P = 7/11 The simplest form .

The square root of 0 = 0.

Rational is defined as a value that can be expressed as a quotient of integers.

For example, 0/1 = 0 and 0/2 = 0. Although 0/0 is undefined, the former examples are still true. Therefore, the square root of 0 is rational.

For your knowledge, the square root of any number is rational, except for negative numbers, which are irrational. This is because two identical integers cannot be multiplied to produce a negative integer.

For instance, the square root of 25 is 5 because 5x5 = 25.

However, the square root of -25 has no real roots because neither -5x-5 nor 5x5 = -25.

Rational!!!!

Casually, any decimal that can be converted to a fraction/ratio is Rational.

1.1 = 1 1/10 = 11/10

Irrational numbers are those that cannot be converted to a fraction/ration.

The most well known IRRATIONAL number is 'pi = 3.141592....'

Irrational numbers are those were the decimals go to infinity AND the decimal digits are not in any regular order.

Rational ; 1/3 = 0.3333....

Irrational ; sqrt(2) = 1.414213562....

I recommend checking online sources such as service manuals or forums dedicated to motorcycle maintenance and repair for schematics specific to the 1993 CBR 900 RR model. You can also try contacting Honda dealerships or authorized service centers for assistance in obtaining the schematics you need.

What do you mean by tox number? When you say urethane do you mean Ethyl carbamate with a CASRN - 51-79-6? If your question is what is the toxicity of ethyl carbamate in humans, I offer the following information: The United States Environmental Protection Agency (USEPA) has determined that there is inadequate data to derive a number to quantify non-carcinogenic health effects by the inhalation route of exposure. The USPEA has not evaluated the carcinogenicity of ethyl carbamate. The International Agency for Research on Cancer has determined that ethyl carbamate is probably carcingenic to humans. If, on the other hand, your question is regarding polyurethane coatings typically used to seal wood floors, among other uses, then the question is what is the toxicity of many other chemicals (other than ethyl carbamate), some known, some unknown, some depending on the manufacturer and formulation.

'3' is RATIONAL.

All numbers are RATIONAL except those were the decimal goes to infinity AND the decimal digits are NOT in any regular order.

pi = 3.1419592.... is probably the most well known IRRATIONAL number. Also the Square Roots of Prime numbers.

NB 3.333.... recurring to infinity is RATIONAL, because it can be converted to a RATIO/Fraction.

Rational

Irrational.

151 is not a perfect square (144 is the nearest one).

square root of 151 is 12.288.

The prefix for irrational is "ir-" which means not or opposite of.

3.625 is RATIONAL, because you have not indicated if it continues to infinity.

To continue to infinity then the number is written as 3.625... (Note the dots).

However, 3.625... is also rational , because it can be converted to a quotient(fraction).

NB IRRATIONAL numbers have their decimal going to infinity AND the decimal digits are not in any regular order.

pi = 3.141592.... Is the most well known irrational number.

Other irrationsal numbers are the square roots of prime numbers.

thereNO!!! Because you can convert it to a quotient(fraction).

However, 1.33333 is a terminal decimal . To indicate it is a decimal to infinity , it is written as 1.33333... Note the use of the 'three or more dots'.

1.33333 Terminal decimal to a fraction is 1 33333/100000 Horrible I know Ugh!!!!!

1.33333... as a decimal to inifinity to a fraction ;-

Let P - 1.33333....

Then

10P = 13.33333....

Subtract

9P = 12 ( Note the deciamsl subtract to 'zero' )

P = 12/9

P = 1 3/9

P = 1 1/3 The answer!!!!

0

'6' is RATIONAL.

Casually IRRATIONAL numbers are those that have decimals going to infinity AND the decimal digits are NOT in any regular order.

'pi' = 3.141592.... is the most well known irrational number.

However, 3.3333... is RATIONAL becaause the decimal digits are in a regular order of '3'.

NO!!!! It is NOT irrational. Reason, it can be converted to a Ratio(fraction).

How do I know???

1. You have not indicated that the decimals go to inifinity.

2. There is a regular order in the digits.

As given it is a terminal decimal 0.57575757

If it was an infinite decimal it should read 0.57575757... ( Note the dots that indicate it contiunes to infinity.

As a terminal decimal its fraction is 57575757/100000000 Ugh!!!!

As an infinite decimal it can be converted to a ratio(fraction)

Hence

Let P = 0.57575757...

&

100P = 57.57575757....

Subtract

99P = 57 ( Notice the repeating decimals subtract to zero.

P = 57/99

Cancel down by '3'

P = 19/33 THe answer

0.575757... = 19/33

&

0.57575757 = 57575757/100000000

2.756 is a rational number. A rational number is any number that can be expressed as an integer, fraction or mixed number, or decimal. Irrational numbers cannot be expressed as simple fractions and do not have repeating decimals such as π (pi), e, and the square root of 2.

An example of a negative irrational number is -√2 (negative square root of 2). This number cannot be expressed as a simple fraction and has a non-repeating, non-terminating decimal expansion.

yes

No, it is an imaginary number.

First of all 'pi' is spelled as 'pi' . NOT 'pie' ; that is the meat pie of apple pie that you eat.

'pi' is the small case classical Greek letter 'p' and mean 'proportion'.

It is the proportional constant between a circles diameter and circumference.

'pi' is an IRRATIONAL number.

Casually this means, that the decimal digits go to infinity, and the digits are NOT in a any regular order. .

More formally 'irrational' means that you cannot form an exact ratio from it's decimal digits.

pi= 3.14 , 3.1416, 3.14592654, 22/7 are all approximations of 'pi'.

Super . Duper Computers have calculated 'pi' to billions of places and still going. !!!!!
