Answer: 5/6
Explanation: Notice that 2/3 and 1/6 are unlike fractions. Our first step when adding unlike fractions is to get a common denominator.
The common denominator of 3 and 6 will be the
least common multiple of 3 and 6 which is 6.
To get a 6 in the denominator of 2/3, we multiply the numerator
and the denominator by 2 which gives us 4/6.
Notice that 1/6 already has a 6 in the denominator.
So we have 4/6 + 1/6.
Now we're adding like fractions so we simply add the numerators,
4 + 1 is 5, and keep the same denominator which is 6.
Notice that 5/6 is in lowest terms so it's our final answer.
