Concept:Convert fractions to decimals to easily compare their values and check which lies within a given range.Explanation:The range is from 3/10=0.3 to 7/10=0.7. Check each option by converting to decimal: Option A: 8/9≈0.888 (greater than 0.7, so outside). Option B: 13/17≈0.764 (greater than 0.7, so outside). Option C: 10/11≈0.909 (greater than 0.7, so outside). Option D: 7/11≈0.636 (lies between 0.3 and 0.7). Thus only 7/11 satisfies 0.3<0.636<0.7.
