So we need to find a number that is between 8/11 and 0.85. This will be easy if we write all numbers in decimal form. 8/11=0.7272727273 and 0.85 is the interval in which we are looking for. The numbers are: A 23/33=0.69696969, B 39/66=0.590909090 C 157/198= 0.792929292 D 88/99=0.888888888. The only number in the interval is C 157/198=0.792929292.
