Why decimal is considered as rational number?
A decimal need not be a rational. A non-terminating, non recurring decimal is an irrational number. Only a terminating decimal or a recurring decimal is rational and that is because such a number can be expressed as a ratio of two integers.
Is decimal a rational number?
It depends. A terminating decimal is a rational number. A decimal which, after a finite number of places, becomes a repeating (or recurrent) decimal is also a rational number. A decimal that is not terminating, nor [eventually] settles into a recurring pattern is not a rational number. Note that the decimal need not become recurring immediately.
What number has one repeated prime factor?
It could be 1/3 when expressed as a decimal is 0.333333 ..... recurring
What does it mean for a number to be rational?
That it can be expressed as a ratio (hence rational) of two integers, the denominator being positive.In decimal representation, it is a necessary and sufficient condition that the number can be expressed as either a terminating decimal or one that becomes a recurring decimal after a finite number of digits.
Is 13.001001001 a rational or irrational number and why?
A rational number is a number that can be expressed as a fraction. This means it can either be a terminating decimal or a recurring decimal. A terminating decimal is a decimal that doesn't recur (repeat for ever). A recurring decimal is a decimal that repeats a pattern of numbers after the decimal point. A good example of this is 1/3. 1/3 = 0.333333.... it is a rational number 13.001001001 is a rational number. Either you meant it to recur or not it makes no difference. 13.001001001 = 13 + 1001001/1000000000 as a terminating decimal 13.001001001....... = 12988/999 as a recurring decimal ---- Examples of numbers that are not rational: sqrt(2), pi, exp they are irrational as they cannot be expressed as fractions.

What is 160 over 9 as a decimal?
Expressed as a decimal number, 160/9 = 17.7 recurring (that is, 17.7777...)

Can an irrational number be expressed as a decimal?
Only as an approximation. An irrational number is equivalent to a non-terminating, non-recurring decimal. That is, an infinitely long decimal number without any repeating pattern.

What is one sixth as a whole number?
One sixth is not a whole number. Expressed as a decimal, it is equal to 0.16 recurring (that is, 0.16666..)
Is 1.57 a rational number and why?
Yes because it can be expressed as a fraction in the form of 157/100
What is 0.1666 as a decimal?
This number already is expressed as a decimal.This number already is expressed as a decimal.This number already is expressed as a decimal.This number already is expressed as a decimal.
233 percent written as a decimal is?
233% is a whole number and so the decimal point is unnecessary. Expressed as a fraction its is a multiple of 2 1/3, as a decimal it is a multiple of 2.33 recurring.
What are the characteristic of irrational?
An irrational number cannot be expressed as a ratio of two integers. The decimal representation of an irrational number is a non-terminating and non-recurring.
