Understanding the Sum of Rational Numbers

When adding 2/3 and 1/6, we need to find a common denominator. In this case, the least common multiple of 3 and 6 is 6.

So, converting 2/3 to have a denominator of 6, we get 4/6. Now, we can add 4/6 and 1/6, resulting in 5/6.

[ \frac{2}{3} + \frac{1}{6} = \frac{4}{6} + \frac{1}{6} = \frac{5}{6} ]

Therefore, the sum of 2/3 and 1/6 is 5/6. Understanding how to add and simplify rational numbers is crucial for success in algebra and other mathematical concepts.
