Find the sum of the fractions

Answer

$\dfrac { 21 } { 20 }$

Find the sum of the fractions

$\dfrac { 1 } { \color{#FF6800}{ 4 } } + \dfrac { 4 } { \color{#FF6800}{ 5 } }$

$ $ The smallest common multiple in denominator is $ 20$

$\dfrac { 1 } { \color{#FF6800}{ 4 } } + \dfrac { 4 } { \color{#FF6800}{ 5 } }$

$\dfrac { 1 } { 4 } + \dfrac { 4 } { 5 }$

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

$\dfrac { 1 \times \color{#FF6800}{ 5 } } { 4 \times \color{#FF6800}{ 5 } } + \dfrac { 4 \times \color{#FF6800}{ 4 } } { 5 \times \color{#FF6800}{ 4 } }$

$\color{#FF6800}{ \dfrac { \color{#FF6800}{ 1 } \color{#FF6800}{ \times } \color{#FF6800}{ 5 } } { \color{#FF6800}{ 4 } \color{#FF6800}{ \times } \color{#FF6800}{ 5 } } } \color{#FF6800}{ + } \color{#FF6800}{ \dfrac { \color{#FF6800}{ 4 } \color{#FF6800}{ \times } \color{#FF6800}{ 4 } } { \color{#FF6800}{ 5 } \color{#FF6800}{ \times } \color{#FF6800}{ 4 } } }$

$ $ Organize the expression $ $

$\color{#FF6800}{ \dfrac { \color{#FF6800}{ 5 } } { \color{#FF6800}{ 20 } } } \color{#FF6800}{ + } \color{#FF6800}{ \dfrac { \color{#FF6800}{ 16 } } { \color{#FF6800}{ 20 } } }$

$\color{#FF6800}{ \dfrac { \color{#FF6800}{ 5 } } { \color{#FF6800}{ 20 } } } \color{#FF6800}{ + } \color{#FF6800}{ \dfrac { \color{#FF6800}{ 16 } } { \color{#FF6800}{ 20 } } }$

$ $ Since the denominator is the same as $ 20 $ , combine the fractions into one $ $

$\color{#FF6800}{ \dfrac { \color{#FF6800}{ 5 } \color{#FF6800}{ + } \color{#FF6800}{ 16 } } { \color{#FF6800}{ 20 } } }$

$\dfrac { \color{#FF6800}{ 5 } \color{#FF6800}{ + } \color{#FF6800}{ 16 } } { 20 }$

$ $ Add $ 5 $ and $ 16$

$\dfrac { \color{#FF6800}{ 21 } } { 20 }$
