$\dfrac{ 2 }{ 3 } + \dfrac{ 4 }{ 5 }$
$\dfrac { 22 } { 15 }$
Find the sum of the fractions
$\dfrac { 2 } { \color{#FF6800}{ 3 } } + \dfrac { 4 } { \color{#FF6800}{ 5 } }$
$ $ The smallest common multiple in denominator is $ 15$
$\dfrac { 2 } { \color{#FF6800}{ 3 } } + \dfrac { 4 } { \color{#FF6800}{ 5 } }$
$\dfrac { 2 } { 3 } + \dfrac { 4 } { 5 }$
$ $ Multiply the denominator and the numerator so that the denominator is the smallest common multiple $ $
$\dfrac { 2 \times \color{#FF6800}{ 5 } } { 3 \times \color{#FF6800}{ 5 } } + \dfrac { 4 \times \color{#FF6800}{ 3 } } { 5 \times \color{#FF6800}{ 3 } }$
$\color{#FF6800}{ \dfrac { 2 \times 5 } { 3 \times 5 } } \color{#FF6800}{ + } \color{#FF6800}{ \dfrac { 4 \times 3 } { 5 \times 3 } }$
$ $ Organize the expression $ $
$\color{#FF6800}{ \dfrac { 10 } { 15 } } \color{#FF6800}{ + } \color{#FF6800}{ \dfrac { 12 } { 15 } }$
$\color{#FF6800}{ \dfrac { 10 } { 15 } } \color{#FF6800}{ + } \color{#FF6800}{ \dfrac { 12 } { 15 } }$
$ $ Since the denominator is the same as $ 15 $ , combine the fractions into one $ $
$\color{#FF6800}{ \dfrac { 10 + 12 } { 15 } }$
$\dfrac { \color{#FF6800}{ 10 } \color{#FF6800}{ + } \color{#FF6800}{ 12 } } { 15 }$
$ $ Add $ 10 $ and $ 12$
$\dfrac { \color{#FF6800}{ 22 } } { 15 }$
