Find the sum or difference of the fractions
$\color{#FF6800}{ - } \color{#FF6800}{ \dfrac { 1 } { 3 } } \color{#FF6800}{ - } \color{#FF6800}{ \dfrac { 2 } { 3 } }$
$ $ Since the denominator is the same as $ 3 $ , combine the fractions into one $ $
$\color{#FF6800}{ \dfrac { - 1 - 2 } { 3 } }$
$\dfrac { \color{#FF6800}{ - } \color{#FF6800}{ 1 } \color{#FF6800}{ - } \color{#FF6800}{ 2 } } { 3 }$
$ $ Find the sum of the negative numbers $ $
$\dfrac { \color{#FF6800}{ - } \color{#FF6800}{ 3 } } { 3 }$
$\dfrac { \color{#FF6800}{ - } \color{#FF6800}{ 3 } } { 3 }$
$ $ Move the minus sign to the front of the fraction $ $
$\color{#FF6800}{ - } \color{#FF6800}{ \dfrac { 3 } { 3 } }$
$\color{#FF6800}{ - } \color{#FF6800}{ \dfrac { 3 } { 3 } }$
$ $ Reduce the fraction to the lowest term $ $
$\color{#FF6800}{ - } \color{#FF6800}{ 1 }$
