15+49\dfrac{1}{5} + \dfrac{4}{9}
15+49\dfrac{1}{5} + \dfrac{4}{9}
Since these fractions have different denominators, we need to find the least common multiple of the denominators
The least common multiple of 5 and 9 is 45, so we need to multiply to make each of the denominators = 45
15∗99=945\dfrac{1}{5} * \dfrac{9}{9} = \dfrac{9}{45}
49∗55=2045\dfrac{4}{9} * \dfrac{5}{5} = \dfrac{20}{45}
Since these fractions have the same denominator, we can just add the numerators
945+2045=2945\dfrac{9}{45} + \dfrac{20}{45} = \dfrac{29}{45}
