Simplification
The numerator and denominator are divided by their greatest common divisor (GCD) so the result is in lowest terms.

Step-by-Step Solution
1.Find the least common denominator: LCM(2, 3) = 6.
2.1/2 + 1/3 = 3/6 + 2/6.
3.Combine the numerators: 3 + 2 = 5.
4.Simplify 5/6.
How Fraction Calculations Work
Addition and subtraction use a common denominator. Multiplication multiplies the numerators and denominators directly, while division multiplies the first fraction by the reciprocal of the second.
Mixed Numbers
A mixed number combines a whole number with a proper fraction, making improper results easier to read.
Exact Arithmetic
Fraction calculations are performed using integer numerators and denominators instead of rounding intermediate decimal values.
