Find the sum of the fractions

Answer

$\dfrac { 31 } { 24 }$

Find the sum of the fractions

$\dfrac { 3 } { \color{#FF6800}{ 8 } } + \dfrac { 11 } { \color{#FF6800}{ 12 } }$

$ $ The smallest common multiple in denominator is $ 24$

$\dfrac { 3 } { \color{#FF6800}{ 8 } } + \dfrac { 11 } { \color{#FF6800}{ 12 } }$

$\dfrac { 3 } { 8 } + \dfrac { 11 } { 12 }$

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

$\dfrac { 3 \times \color{#FF6800}{ 3 } } { 8 \times \color{#FF6800}{ 3 } } + \dfrac { 11 \times \color{#FF6800}{ 2 } } { 12 \times \color{#FF6800}{ 2 } }$

$\color{#FF6800}{ \dfrac { \color{#FF6800}{ 3 } \color{#FF6800}{ \times } \color{#FF6800}{ 3 } } { \color{#FF6800}{ 8 } \color{#FF6800}{ \times } \color{#FF6800}{ 3 } } } \color{#FF6800}{ + } \color{#FF6800}{ \dfrac { \color{#FF6800}{ 11 } \color{#FF6800}{ \times } \color{#FF6800}{ 2 } } { \color{#FF6800}{ 12 } \color{#FF6800}{ \times } \color{#FF6800}{ 2 } } }$

$ $ Organize the expression $ $

$\color{#FF6800}{ \dfrac { \color{#FF6800}{ 9 } } { \color{#FF6800}{ 24 } } } \color{#FF6800}{ + } \color{#FF6800}{ \dfrac { \color{#FF6800}{ 22 } } { \color{#FF6800}{ 24 } } }$

$\color{#FF6800}{ \dfrac { \color{#FF6800}{ 9 } } { \color{#FF6800}{ 24 } } } \color{#FF6800}{ + } \color{#FF6800}{ \dfrac { \color{#FF6800}{ 22 } } { \color{#FF6800}{ 24 } } }$

$ $ Since the denominator is the same as $ 24 $ , combine the fractions into one $ $

$\color{#FF6800}{ \dfrac { \color{#FF6800}{ 9 } \color{#FF6800}{ + } \color{#FF6800}{ 22 } } { \color{#FF6800}{ 24 } } }$

$\dfrac { \color{#FF6800}{ 9 } \color{#FF6800}{ + } \color{#FF6800}{ 22 } } { 24 }$

$ $ Add $ 9 $ and $ 22$

$\dfrac { \color{#FF6800}{ 31 } } { 24 }$
