$\large\text{Hey there!}$

$\mathsf{Is\ \dfrac{1}{8}\ greater\ than\ or\ less\ than\ \dfrac{2}{5}\ ?}$

$\large\text{Personally, if you convert your fractions into decimals it can be easier to}\\\large\text{to answer your question. Or you could even match it with the LCD}\\\large\text{if it is easier for you!}$

$\mathsf{\dfrac{1}{8}=0.125} \\\\\mathsf{\dfrac{2}{5}=0.40}$

$\large\text{The\ LCD (Lowest Common Denominator) is 40}$

$\mathsf{Match\ your\ fractions\ with\ your\ LCD}\\\\\boxed{\mathsf{\dfrac{1}{8}}}\boxed{\mathsf{\dfrac{2}{5}}}\\\boxed{\mathsf{\dfrac{5}{40}}}\boxed{\mathsf{\dfrac{16}{40}}}$
