Find the sum of the fractions

Answer

$\left( + \dfrac{ 1 }{ 5 } \right) + \left( + \dfrac{ 2 }{ 15 } \right)$

$\dfrac { 1 } { 3 }$

Find the sum of the fractions

$\dfrac { 1 } { \color{#FF6800}{ 5 } } + \dfrac { 2 } { \color{#FF6800}{ 15 } }$

$ $ The smallest common multiple in denominator is $ 15$

$\dfrac { 1 } { \color{#FF6800}{ 5 } } + \dfrac { 2 } { \color{#FF6800}{ 15 } }$

$\dfrac { 1 } { 5 } + \dfrac { 2 } { 15 }$

$ $ Multiply the denominator and the numerator so that the denominator is the smallest common multiple $ $

$\dfrac { 1 \times \color{#FF6800}{ 3 } } { 5 \times \color{#FF6800}{ 3 } } + \dfrac { 2 } { 15 }$

$\color{#FF6800}{ \dfrac { 1 \times 3 } { 5 \times 3 } } \color{#FF6800}{ + } \color{#FF6800}{ \dfrac { 2 } { 15 } }$

$ $ Organize the expression $ $

$\color{#FF6800}{ \dfrac { 3 } { 15 } } \color{#FF6800}{ + } \color{#FF6800}{ \dfrac { 2 } { 15 } }$

$ $ Since the denominator is the same as $ 15 $ , combine the fractions into one $ $

$\color{#FF6800}{ \dfrac { 3 + 2 } { 15 } }$

$\dfrac { \color{#FF6800}{ 3 } \color{#FF6800}{ + } \color{#FF6800}{ 2 } } { 15 }$

$ $ Add $ 3 $ and $ 2$

$\dfrac { \color{#FF6800}{ 5 } } { 15 }$

$\color{#FF6800}{ \dfrac { 5 } { 15 } }$

$ $ Reduce the fraction to the lowest term $ $

$\color{#FF6800}{ \dfrac { 1 } { 3 } }$
