$10$

Calculate the value

$\dfrac { 5 } { 2 } \color{#FF6800}{ \times } \color{#FF6800}{ 4 }$

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

$\dfrac { 5 } { 2 } \color{#FF6800}{ \times } \color{#FF6800}{ \dfrac { \color{#FF6800}{ 4 } } { \color{#FF6800}{ 1 } } }$

$\dfrac { 5 } { \color{#FF6800}{ 2 } } \times \dfrac { \color{#FF6800}{ 4 } } { 1 }$

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

$\dfrac { 5 } { \color{#FF6800}{ 1 } } \times \dfrac { \color{#FF6800}{ 2 } } { 1 }$

$\color{#FF6800}{ \dfrac { \color{#FF6800}{ 5 } } { \color{#FF6800}{ 1 } } } \color{#FF6800}{ \times } \color{#FF6800}{ \dfrac { \color{#FF6800}{ 2 } } { \color{#FF6800}{ 1 } } }$

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

$\color{#FF6800}{ \dfrac { \color{#FF6800}{ 5 } \color{#FF6800}{ \times } \color{#FF6800}{ 2 } } { \color{#FF6800}{ 1 } \color{#FF6800}{ \times } \color{#FF6800}{ 1 } } }$

$\dfrac { \color{#FF6800}{ 5 } \color{#FF6800}{ \times } \color{#FF6800}{ 2 } } { 1 \times 1 }$

$ $ Multiply $ 5 $ and $ 2$

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

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

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

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

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

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

$\color{#FF6800}{ 10 }$
