We want a fraction that satisfies this equation, and therefore the top has to multiply to 25, and the bottom to 66. We can figure out the missing munber by dividing 25/5, getting us 5 as our numerator. We can do the same for the denominator, 99/11 = 6. Therefore, out fraction is 5/6. Hope this helped, and let me know if you have any more questions.
