$\dfrac{ 5 }{ 4 } - \dfrac{ 1 }{ 2 }$
$\dfrac { 3 } { 4 }$
Find the difference
$\dfrac { 5 } { \color{#FF6800}{ 4 } } - \dfrac { 1 } { \color{#FF6800}{ 2 } }$
$ $ The smallest common multiple in denominator is $ 4$
$\dfrac { 5 } { \color{#FF6800}{ 4 } } - \dfrac { 1 } { \color{#FF6800}{ 2 } }$
$\dfrac { 5 } { 4 } - \dfrac { 1 } { 2 }$
$ $ Multiply the denominator and the numerator so that the denominator is the smallest common multiple $ $
$\dfrac { 5 } { 4 } - \dfrac { 1 \times \color{#FF6800}{ 2 } } { 2 \times \color{#FF6800}{ 2 } }$
$\color{#FF6800}{ \dfrac { 5 } { 4 } } \color{#FF6800}{ - } \color{#FF6800}{ \dfrac { 1 \times 2 } { 2 \times 2 } }$
$ $ Organize the expression $ $
$\color{#FF6800}{ \dfrac { 5 } { 4 } } \color{#FF6800}{ - } \color{#FF6800}{ \dfrac { 2 } { 4 } }$
$\color{#FF6800}{ \dfrac { 5 } { 4 } } \color{#FF6800}{ - } \color{#FF6800}{ \dfrac { 2 } { 4 } }$
$ $ Since the denominator is the same as $ 4 $ , combine the fractions into one $ $
$\color{#FF6800}{ \dfrac { 5 - 2 } { 4 } }$
$\dfrac { \color{#FF6800}{ 5 } \color{#FF6800}{ - } \color{#FF6800}{ 2 } } { 4 }$
$ $ Subtract $ 2 $ from $ 5$
$\dfrac { \color{#FF6800}{ 3 } } { 4 }$
