Best ResponseYou've already chosen the best response.0a rational number can be written as \(a/b\) where a and b are integers

Best ResponseYou've already chosen the best response.2another clue is if you write the number as a decimal, you can predict the digits. for example, pi is irrational because we have to calculate each digit in its decimal. Knowing pi= 3.14159 does not tell us what the next digit is. (People have calculated this out to millions of digits... no pattern) on the other hand 1/7 = 0.142857142857142857... (it keeps repeating 142857...) that means it is rational

Best ResponseYou've already chosen the best response.2almost all "roots" (example sqrt(2) ) are irrational except for perfect squares such as sqrt(4) = 2.0 (and here we know its decimals.. all 0's)

Best ResponseYou've already chosen the best response.2so if you see a fraction of integers, it is rational if you see an irrational number times or divided by a nice number, it stays irrational the only time I can think of to get a rational number from irrationals is if we see for example, \[ \frac{\pi}{\pi} = 1 \]
