Final answer:
To divide fractions, multiply the first fraction by the reciprocal of the second fraction. In this case, 5/6 divided by 9/10 is equal to 25/27.
This correct answer is none of the above.
Step-by-step explanation:
To divide fractions, we need to multiply the first fraction by the reciprocal of the second fraction.
The reciprocal of a fraction is obtained by swapping the numerator and the denominator. 5/6 divided by 9/10 is equal to (5/6) * (10/9) = 50/54.
However, we can simplify this fraction by dividing both the numerator and denominator by their greatest common divisor, which is 2. So, 50/54 = 25/27.
This correct answer is none of the above.
