$\dfrac { 12 } { 7 }$
Find the difference
$\color{#FF6800}{ 4 \dfrac { 3 } { 7 } } - 2 \dfrac { 5 } { 7 }$
$ $ Convert mixed number into improper fraction $ $
$\color{#FF6800}{ \dfrac { 31 } { 7 } } - 2 \dfrac { 5 } { 7 }$
$\dfrac { 31 } { 7 } \color{#FF6800}{ - } \color{#FF6800}{ 2 \dfrac { 5 } { 7 } }$
$ $ Convert mixed number into improper fraction $ $
$\dfrac { 31 } { 7 } \color{#FF6800}{ - } \color{#FF6800}{ \dfrac { 19 } { 7 } }$
$\color{#FF6800}{ \dfrac { 31 } { 7 } } \color{#FF6800}{ - } \color{#FF6800}{ \dfrac { 19 } { 7 } }$
$ $ Since the denominator is the same as $ 7 $ , combine the fractions into one $ $
$\color{#FF6800}{ \dfrac { 31 - 19 } { 7 } }$
$\dfrac { \color{#FF6800}{ 31 } \color{#FF6800}{ - } \color{#FF6800}{ 19 } } { 7 }$
$ $ Subtract $ 19 $ from $ 31$
$\dfrac { \color{#FF6800}{ 12 } } { 7 }$
