Is the square root of 19 a rational number?

No. 19 is a prime number, and all prime numbers have irrational roots.


Is 7.76 irrational or rational?

Rational , because it can be converted to a fraction. 7.76 = 7 76/100 = 7 38/50 = 7 19/25 NB Irrational numbers cannot be converted tpo a quotient. 'pi = 3.1415936.... ' it the most famous irrational number. When you are given pi = 3.14' in school , this is only an approximation.

Is -19 a rational number?

-- Any number that you can completely write down using digits, and a decimal point or fraction bar if needed, is rational. -- A rational number is defined as one that can be written as a fraction using whole numbers. -19 can be written as the fraction -19/1 .


All real numbers are irrational?

A mathematical approach:Yes they are. Irrational Numbers are very real, for example - the square root of two - which is irrational (but can be plotted in a number line without difficulty with a compass and straight edge). All numbers you can think of (even if you cant white them out) are real numbers.They are real, but they can't be expressed as fractions.A philosophical approach:According to ME, there should be a limit. If there is a number which is not ending, we can't say that it is a number because it has not ended yet, its not a complete number. That's why, any number which is not ending is not a number, so irrational numbers and some rational numbers are not numbers and we can't plot them on real line, no matter how much depth we are into it. If there is a number 1.0000... (100 million 0's) ...1, we can plot it by dividing real line into required many parts but we cant plot a number like 1.1111....1111....(up to, we don't know), actually that's not a number yet.Maths should be changed.
