well since we know that 3 can go into both those numbers we can take the equation 33 over 81 and further simplify it by dividing it by 3 over 3 this equalling 11 over 27. And since 11 is a prime number (so is 27) we know that this is the correct answer.

Correct answer but wromg reasoning towards the end.
1. 27 is NOT a prime: 27 = 3*9
2. The fact that 11 is a prime is not sufficient for the fraction to be in its lowest form: 11/22 simplifies to 1/2.
3. Nor is primality a necessary condition. 4 is not a prime, 9 is not a prime but 4/9 cannot be simplified.
4. What matters is that the numerator and the denoinator are COPRIME, thatis, they have no factor in common.
Also, 33/81 is not an equation but an expression.
33/81 = 11/27
33/4 = 81/4 or 8.25
11 over 27 because they are both divisible by 3. 33/81=11/27
33/81 simplified is 11/27........ 49/105 simplified is 7/15!!!!!!!!!!!!
Since 32 and 85 share no common factors other than 1, the proper fraction 32/85 is already expressed in its simplest form.
33/81Divide numerator and denominator by 3:11/27
81 over 100 is already in simplest form.
5/81 is the simplest form.
40/81 is in its simplest form.
64/81 is in its simplest form.
The simplest form for 81 over 90 is 9/10
17/81 is in its simplest form.
