14+38\dfrac{1}{4} + \dfrac{3}{8}
14+38\dfrac{1}{4} + \dfrac{3}{8}
Since these fractions have different denominators, we need to find the least common multiple of the denominators
The least common multiple of 4 and 8 is 8, so we need to multiply to make each of the denominators = 8
14∗22=28\dfrac{1}{4} * \dfrac{2}{2} = \dfrac{2}{8}
38∗11=38\dfrac{3}{8} * \dfrac{1}{1} = \dfrac{3}{8}
Since these fractions have the same denominator, we can just add the numerators
28+38=58\dfrac{2}{8} + \dfrac{3}{8} = \dfrac{5}{8}
