NO!!!
As given it is a terminating decimal, and as a fraction it is 6666/10000
However,as a recurring decimal to infinity, it can be converted to a ratio/fraction .
Hence
Let P = 0.66666....
10P = 6.66666....
Subtract
9P = 6.0 (Note the recurring decimal subtract to 'zero'.
Hence
9P = 6
P = 6/9
Cancel down by '3'
P = 2/3
NB Resurring decimals to infinity are written as 0.666... ( Note the three or more dots. This indicates to mathematicians, that it recurs to infinity, otherwise it is a terminating decimal.
NNB Irrational Numbers are those that recur to inifinity AND the decimal digits are not in any regular order. . 'pi' 3.141592.... being the most well known irrational number.
The sum of a rational and irrational number must be an irrational number.
No, 3.56 is not an irrational number. 3.56 is rational.
rational * irrational = irrational.
-Pi is irrational, because it does not terminate or repeat. Whenever you multiply an irrational number by a rational number (-1), the result is an irrational number.
Any irrational number, when multiplied by 0.5 will give an irrational number.
An irrational number.
No. The sum of an irrational number and any other [real] number is irrational.
The sum of a rational and irrational number must be an irrational number.
No, 3.56 is not an irrational number. 3.56 is rational.
rational * irrational = irrational.
-Pi is irrational, because it does not terminate or repeat. Whenever you multiply an irrational number by a rational number (-1), the result is an irrational number.
A negative irrational number can be thought of as an irrational number multiplied by -1, or an irrational number with a minus sign in front of it.
At least one of the factors has to be irrational.* An irrational number times ANY number (except zero) is irrational. * The product of two irrational numbers can be either rational or irrational.
Any irrational number, when multiplied by 0.5 will give an irrational number.
Any irrational number, added to 0.4 will give an irrational number.
When added to a rational number, any irrational number will produce an irrational number.also, when added to an irrational number, any rational number will produce an irrational number.
Such a sum is always irrational.
