$120 \times \dfrac{ 30 }{ 100 }$
$36$
Calculate the value
$120 \times \color{#FF6800}{ \dfrac { 30 } { 100 } }$
$ $ Reduce the fraction to the lowest term $ $
$120 \times \color{#FF6800}{ \dfrac { 3 } { 10 } }$
$\color{#FF6800}{ 120 } \times \dfrac { 3 } { 10 }$
$ $ Natural numbers can be expressed as fractions with a denominator of 1 $ $
$\color{#FF6800}{ \dfrac { 120 } { 1 } } \times \dfrac { 3 } { 10 }$
$\dfrac { \color{#FF6800}{ 120 } } { 1 } \times \dfrac { 3 } { \color{#FF6800}{ 10 } }$
$ $ Reduce all denominators and numerators that can be reduced $ $
$\dfrac { \color{#FF6800}{ 12 } } { 1 } \times \dfrac { 3 } { \color{#FF6800}{ 1 } }$
$\color{#FF6800}{ \dfrac { 12 } { 1 } } \color{#FF6800}{ \times } \color{#FF6800}{ \dfrac { 3 } { 1 } }$
$ $ numerator multiply between numerator, and denominators multiply between denominators $ $
$\color{#FF6800}{ \dfrac { 12 \times 3 } { 1 \times 1 } }$
$\dfrac { \color{#FF6800}{ 12 } \color{#FF6800}{ \times } \color{#FF6800}{ 3 } } { 1 \times 1 }$
$ $ Multiply $ 12 $ and $ 3$
$\dfrac { \color{#FF6800}{ 36 } } { 1 \times 1 }$
$\dfrac { 36 } { \color{#FF6800}{ 1 } \times 1 }$
$ $ Multiplying any number by 1 does not change the value $ $
$\dfrac { 36 } { \color{#FF6800}{ 1 } }$
$\dfrac { 36 } { \color{#FF6800}{ 1 } }$
$ $ If the denominator is 1, the denominator can be removed $ $
$\color{#FF6800}{ 36 }$
