1) Among all fractions \(x\) that have a positive integer numerator and denominator and satisfy \(\frac{9}{11} \le x \le \frac{11}{13}\) which fraction has the smallest denominator?
I think this goes like this:
11/13 - 9/11 = The common denominator of 11 and 13 is 143
[ 121 - 117] / 143 =
4 / 143
Why didn't you ask for help earlier?
