What ratio, expressed as a percentage, is between 11 and 12?

The ratio between two numbers can be calculated by dividing one number by the other and then multiplying by 100 to express it as a percentage. In this case, to find the ratio between 11 and 12, you would divide 11 by 12, which equals approximately 0.9167. When you multiply this number by 100, the result is about 91.67%.

In this context, the correct choice is the Mortgage Constant, which reflects the proportion of a loan payment to the amount of the loan. It essentially represents the conversion of a present value of money into periodic payments. The ratio being assessed reflects an understanding of mathematical relationships that can be critical in finance and real estate analysis, particularly when evaluating loan payments or financial relationships involving mortgages.

The other options do not pertain specifically to the concept of a numerical ratio between two figures. Improvement refers to the increase in a property's value or function, Overall Rate usually relates to capitalization rates in real estate, and Vacancy deals with the proportion of unoccupied space in a property. Each of these terms serves different purposes within the field and does not directly relate to the simple mathematical concept of comparing two numbers as a ratio.
