If you can completely write a number, using digits, fractions and decimals,
then the number is rational. You appear to have done that.
Irrational.
If you can completely write a number, using digits, fractions and decimals, then the number is rational. You appear to have accomplished that.
The product of a rational and irrational number can be rational if the rational is 0. Otherwise it is always irrational.
Yes, 27 is a real number. Real numbers include all rational and irrational numbers, and 27 is a rational number because it can be expressed as a fraction, 27/1.
No.A rational times an irrational is never rational. It is always irrational.
No, it is rational.
5.4 = 5 2/5 = 27/5 so it is a rational number.
10.01 is a rational number
No it is rational. It can be written as 27/10.
The square root of 27 is an irrational number
Rational
RATIONAL , because you can convert it to a RATION (FRACTION). Method Let P = 0.272727.... Then 100P = 27.272727.... Subtract 99P = 27 (Note the decimals to infinity subtract to zero. P = 27/99 Cancel down by '9' P = 3/11 ( Which is a RATIO/rational). Since both '3' & '11' are prime numbers this will not cancel down any further. Hence 3/11 = 0.272727....
It is a rational number.
is 34.54 and irrational or rational. number
it is a rational number but 4.121314..... is an irrational no
Irrational.
Such a product is always irrational - unless the rational number happens to be zero.
