Answer:
3/4.
Explanation:
Find the prime factors:
198 = 2 * 99
99 = 3 * 3 * 11
So 198 = 2 * 3 * 3 * 11.
264 = 4 * 66 = 2 *2 * 66
66 = 2 * 3 * 11
So 264 = 2 * 2 * 2 * 3 * 11.
Now we find the Greatest common factor os the 2 numbers:
It is 2 * 3 * 11 = 66.
Therefore we can now simplify the fraction:
198/66 / 264/66
= 3/4.
