Find the sum of the fractions
$\dfrac{ 1 }{ 6 } + \dfrac{ 2 }{ 9 }$
$\dfrac { 7 } { 18 }$
Find the sum of the fractions
$\dfrac { 1 } { \color{#FF6800}{ 6 } } + \dfrac { 2 } { \color{#FF6800}{ 9 } }$
 The smallest common multiple in denominator is $18$
$\dfrac { 1 } { \color{#FF6800}{ 6 } } + \dfrac { 2 } { \color{#FF6800}{ 9 } }$
$\dfrac { 1 } { 6 } + \dfrac { 2 } { 9 }$
 Multiply the denominator and the numerator so that the denominator is the smallest common multiple 
$\dfrac { 1 \times \color{#FF6800}{ 3 } } { 6 \times \color{#FF6800}{ 3 } } + \dfrac { 2 \times \color{#FF6800}{ 2 } } { 9 \times \color{#FF6800}{ 2 } }$
$\color{#FF6800}{ \dfrac { 1 \times 3 } { 6 \times 3 } } \color{#FF6800}{ + } \color{#FF6800}{ \dfrac { 2 \times 2 } { 9 \times 2 } }$
 Organize the expression 
$\color{#FF6800}{ \dfrac { 3 } { 18 } } \color{#FF6800}{ + } \color{#FF6800}{ \dfrac { 4 } { 18 } }$
$\color{#FF6800}{ \dfrac { 3 } { 18 } } \color{#FF6800}{ + } \color{#FF6800}{ \dfrac { 4 } { 18 } }$
 Since the denominator is the same as $18$ , combine the fractions into one 
$\color{#FF6800}{ \dfrac { 3 + 4 } { 18 } }$
$\dfrac { \color{#FF6800}{ 3 } \color{#FF6800}{ + } \color{#FF6800}{ 4 } } { 18 }$
 Add $3$ and $4$
$\dfrac { \color{#FF6800}{ 7 } } { 18 }$
