Question

87/14:31/14+68/14:31/14

Answer 1

\(\dfrac{87}{14}:\dfrac{31}{14}+\dfrac{68}{14}:\dfrac{31}{14}\)

\(=\left(\dfrac{87}{14}+\dfrac{68}{14}\right)x\dfrac{14}{31}\)

=\(\dfrac{155}{14}x\dfrac{14}{31}\)

\(=\dfrac{155}{31}=5\)

Answer 2

\(\dfrac{87}{14}:\dfrac{31}{14}+\dfrac{68}{14}:\dfrac{31}{14}\)

\(=\left(\dfrac{87}{14}+\dfrac{68}{14}\right):\dfrac{31}{14}\)

\(=\dfrac{155}{14}:\dfrac{31}{14}\)

\(=\dfrac{155}{14}.\dfrac{14}{31}=\dfrac{2170}{434}=5\)
