The question is asking to choose the largest proper fraction from the given options. The options are presented as ratios of two numbers, where the first number is the numerator and the second number is the denominator. To find the largest proper fraction, we need to compare their values. A proper fraction is a fraction where the numerator is smaller than the denominator. All the given options are proper fractions. We can compare them by converting them to decimals or by finding a common denominator. Comparing the given fractions: 11/10: This is not a proper fraction as the numerator is greater than the denominator. If it were intended as a ratio, we would consider it as is. 12/11: This is not a proper fraction. 13/10: This is not a proper fraction. 9/17: This is a proper fraction. However, the image displays the options as "11 : 10", "12 : 11", "13 : 10", "9 : 17". These likely represent fractions. Let's assume they are indeed fractions: 11/10, 12/11, 13/10, and 9/17. If we interpret these as fractions: 11/10 = 1.1 12/11 ≈ 1.0909 13/10 = 1.3 9/17 ≈ 0.5294 If these are indeed fractions and the question is to find the largest proper fraction, then there seems to be a misunderstanding in the problem statement or the options provided, as 11/10, 12/11, and 13/10 are improper fractions. The only proper fraction is 9/17. Let's re-evaluate based on the common interpretation of such questions in an educational context where the goal is to find the largest value among options, and
