Question

What is 66 2/3 as a fraction

Answer 1

66 x 3 = 198
198 + 2 = 200
200 / 3

As an improper fraction, anyway. 66 2/3 is already *technically* a fraction. 

Answer 2

First you would get the whole number, multiply by the denominator and add the numerator.
So 66x3=198.  198+2=200.
So the answer is 200/3 (the denominator stays the same)
