You are adding 1 to the numerator, which means that the next numerator in the sequence is going to be 5. You are multiplying the denominator by 3, so it means that the next denominator in the sequence is going to be 162.
The answer is 5/162.
0.666... is equal to 2/3 and 0.75 is equal to 3/4. 2/3 x 3/4= 6/12 which simplifies to 1/2 or 0.5.
To divide, multiply the first number by the reciprocal of the second, so 2/3 x 4/3 = 8/9.
