Rational number or irrational? And why? I have been challenged in my college algebra class to determine whether or not .12122122212222122221222221... (continuing forever)is a rational number or not. I need to prove one way or the other. I am lost! :-( I k...

Is .121221222122221... (the pattern in this number continues forever) a rational number or irrational number? Why? (my research is listed in a previous question post, but I'm stuck!!! Please help!) :-)

F=G((mM)/(d^2)), solve for d

60% is the same as writing 60/100. If you reduce the fraction, 60/100, you first need to find a common factor. Start with the number 2. 2 goes into 60, 30 times. 2 goes into 100, 50 times. So now you have the fraction 30/50. Keep reducing with common fact...
