Is the number 6 rational or irrational?
'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'.
Can an irrational number divided by an irrational number equals an irrational number?
Yes, an irrational number divided by an irrational number will usually be an irrational number, but not always. For example, pi / (3pi) is 1/3, which is a rational number, but pi/e is an irrational number.
Is 15.2 a rationtal number or irrational number?
RATIONAL. Any DEcimal Number that can be made into a fraction/ratio is RATIONAL. So 0.3333..... is Rational as its fraction is '1/3' BUT pi = 3.141592.... is IRRATIONAL because in casual terms the decimal digits are NOT in any regular order. As a rough rule, All numbers are rational except. ;- pi , 'e' and the square roots of prime numbers. NB There are other Irrational numbers too!!!!!
Is 0.6 a rational number or an irrational number?
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.
Is the sum of two POSITIVE irrational numbers ALWAYS irrational?
No. Two irrational numbers can be added to be rational. For example, 1/3 + 2/3 = 3/3. 1/3 and 2/3 are both irrational, but 3/3 = 1, which is rational.
