Calculate the value

Answer

$\dfrac{ 12 }{ 40 } \times 100$

$30$

Calculate the value

$\color{#FF6800}{ \dfrac { 12 } { 40 } } \times 100$

$ $ Reduce the fraction to the lowest term $ $

$\color{#FF6800}{ \dfrac { 3 } { 10 } } \times 100$

$\dfrac { 3 } { 10 } \color{#FF6800}{ \times } \color{#FF6800}{ 100 }$

$ $ Natural numbers can be expressed as fractions with a denominator of 1 $ $

$\dfrac { 3 } { 10 } \color{#FF6800}{ \times } \color{#FF6800}{ \dfrac { 100 } { 1 } }$

$\dfrac { 3 } { \color{#FF6800}{ 10 } } \times \dfrac { \color{#FF6800}{ 100 } } { 1 }$

$ $ Reduce all denominators and numerators that can be reduced $ $

$\dfrac { 3 } { \color{#FF6800}{ 1 } } \times \dfrac { \color{#FF6800}{ 10 } } { 1 }$

$\color{#FF6800}{ \dfrac { 3 } { 1 } } \color{#FF6800}{ \times } \color{#FF6800}{ \dfrac { 10 } { 1 } }$

$ $ numerator multiply between numerator, and denominators multiply between denominators $ $

$\color{#FF6800}{ \dfrac { 3 \times 10 } { 1 \times 1 } }$

$\dfrac { \color{#FF6800}{ 3 } \color{#FF6800}{ \times } \color{#FF6800}{ 10 } } { 1 \times 1 }$

$ $ Multiply $ 3 $ and $ 10$

$\dfrac { \color{#FF6800}{ 30 } } { 1 \times 1 }$

$\dfrac { 30 } { \color{#FF6800}{ 1 } \times 1 }$

$ $ Multiplying any number by 1 does not change the value $ $

$\dfrac { 30 } { \color{#FF6800}{ 1 } }$

$ $ If the denominator is 1, the denominator can be removed $ $

$\color{#FF6800}{ 30 }$
