Incorrect
Add fractions with unlike denominators by transforming the fractions so that they have the like denominatorsStart with listing out multiples of `8` and `4`Multiples of `8`:$$\color{#004ec4}{8}\;\;16\;\;24$$Multiples of `4`:$$4\;\;\color{#004ec4}{8}\;\;12$$The `LCD` of `8` and `4` is `8`Use the `LCD` as the denominator for both fractions then proceed with adding.`3/8+1/4` `=` $$\frac{3}{8}+\frac{1\times\color{#CC0000}{2}}{4\times\color{#CC0000}{2}}$$ Multiply by `2` so that the denominator becomes `8` `=` $$\frac{3}{\color{#004ec4}{8}}+\frac{2}{\color{#004ec4}{8}}$$ Add the numerators `=` $$\frac{5}{8}$$ Keep the same denominator `5/8`
