$\dfrac { 2 } { 5 }$
Find the difference
$\color{#FF6800}{ \dfrac { 4 } { 5 } } \color{#FF6800}{ - } \color{#FF6800}{ \dfrac { 2 } { 5 } }$
$ $ Since the denominator is the same as $ 5 $ , combine the fractions into one $ $
$\color{#FF6800}{ \dfrac { 4 - 2 } { 5 } }$
$\dfrac { \color{#FF6800}{ 4 } \color{#FF6800}{ - } \color{#FF6800}{ 2 } } { 5 }$
$ $ Subtract $ 2 $ from $ 4$
$\dfrac { \color{#FF6800}{ 2 } } { 5 }$
