13+29\dfrac{1}{3} + \dfrac{2}{9}
13+29\dfrac{1}{3} + \dfrac{2}{9}
Since these fractions have different denominators, we need to find the least common multiple of the denominators
The least common multiple of 3 and 9 is 9, so we need to multiply to make each of the denominators = 9
13∗33=39\dfrac{1}{3} * \dfrac{3}{3} = \dfrac{3}{9}
29∗11=29\dfrac{2}{9} * \dfrac{1}{1} = \dfrac{2}{9}
Since these fractions have the same denominator, we can just add the numerators
39+29=59\dfrac{3}{9} + \dfrac{2}{9} = \dfrac{5}{9}
