Formula
Calculate the value
$\dfrac{ 2 }{ 7 } \times \dfrac{ 5 }{ 8 } \times \dfrac{ 3 }{ 10 }$
$\dfrac { 3 } { 56 }$
Calculate the value
$\dfrac { \color{#FF6800}{ 2 } } { 7 } \times \dfrac { \color{#FF6800}{ 5 } } { \color{#FF6800}{ 8 } } \times \dfrac { 3 } { \color{#FF6800}{ 10 } }$
 Reduce all denominators and numerators that can be reduced 
$\dfrac { \color{#FF6800}{ 1 } } { 7 } \times \dfrac { \color{#FF6800}{ 1 } } { \color{#FF6800}{ 4 } } \times \dfrac { 3 } { \color{#FF6800}{ 2 } }$
$\color{#FF6800}{ \dfrac { 1 } { 7 } } \color{#FF6800}{ \times } \color{#FF6800}{ \dfrac { 1 } { 4 } } \color{#FF6800}{ \times } \color{#FF6800}{ \dfrac { 3 } { 2 } }$
 numerator multiply between numerator, and denominators multiply between denominators 
$\color{#FF6800}{ \dfrac { 1 \times 1 \times 3 } { 7 \times 4 \times 2 } }$
$\dfrac { \color{#FF6800}{ 1 } \color{#FF6800}{ \times } \color{#FF6800}{ 1 } \times 3 } { 7 \times 4 \times 2 }$
 Multiplying any number by 1 does not change the value 
$\dfrac { 3 } { 7 \times 4 \times 2 }$
$\dfrac { 3 } { \color{#FF6800}{ 7 } \color{#FF6800}{ \times } \color{#FF6800}{ 4 } \color{#FF6800}{ \times } \color{#FF6800}{ 2 } }$
 Multiply the numbers 
$\dfrac { 3 } { \color{#FF6800}{ 56 } }$
