Fractions are easier compared when they have the same denominator.First, make sure the two fractions have the same denominatorIdentify the `LCD` of `3` and `8` by listing their multiplesMultiples of `3`:$$3\;\;6\;\;9\;\;12\;\;15\;\;18\;\;21\;\;\color{#004ec4}{24}\;\;27$$Multiples of `8`:$$8\;\;16\;\;21\;\;\color{#004ec4}{24}\;\;32$$The LCD of `3` and `8` is `24`Convert the two fractions so that their denominator is `24`$$\frac{2\times\color{#CC0000}{8}}{3\times\color{#CC0000}{8}}$$ `=` $$\frac{16}{\color{#004ec4}{24}}$$ $$\frac{5\times\color{#CC0000}{3}}{8\times\color{#CC0000}{3}}$$ `=` $$\frac{15}{\color{#004ec4}{24}}$$ Choose the fraction with a larger numerator`16/24` or `15/24`Since `16/24` has a larger numerator, `2/3` is the larger fraction`2/3`

.Fractions are easier compared when they have the same denominator.First, make sure the three fractions have the same denominatorSince `4`, `5` and `3` doesn’t have any immediate common multiple, simply multiply them to find their `LCD``4xx5xx3` `=` `60` The `LCD` of `4`, `5` and `3` is `60`Transform the fractions so that they have `60` as the denominator$$\frac{3\times\color{#CC0000}{15}}{4\times\color{#CC0000}{15}}$$ `=` $$\frac{45}{\color{#004ec4}{60}}$$ $$\frac{4\times\color{#CC0000}{12}}{5\times\color{#CC0000}{12}}$$ `=` $$\frac{48}{\color{#004ec4}{60}}$$ $$\frac{2\times\color{#CC0000}{20}}{3\times\color{#CC0000}{20}}$$ `=` $$\frac{40}{\color{#004ec4}{60}}$$ Finally, arrange the fractions from the largest numerator to the smallest$$\frac{45}{60},\frac{48}{60},\frac{40}{60}$$ `=` $$\frac{48}{60},\frac{45}{60},\frac{40}{60}$$ `=` `4/5,3/4,2/3` Reduce back to lowest terms `4/5,3/4,2/3`
