There is not enough information given to determine the LCD, but we can look at the answer choices to see which one(s) could potentially be the LCD. The LCD must be a multiple of all the denominators involved, so we can check each answer choice to see if it is a multiple of the denominators. 450 is divisible by 5 and 90, so it could potentially be the LCD. However, 5 and 55 are not multiples of 90, so they cannot be the LCD. Therefore, the best choice is C, 90. Unfortunately, there is not enough information provided to determine the least common denominator.
