Solve the equation.

$\begin{gathered} (5)/(9)d=(9)/(10) \\ d=(9\cdot9)/(5\cdot10) \\ =(81)/(50) \\ =1(31)/(50) \end{gathered}$

To check substitute the 81/50 for d in the equation.

$\begin{gathered} (5)/(9)\cdot(81)/(50)=(5)/(9)\cdot(9\cdot9)/(5\cdot10) \\ =(9)/(10) \end{gathered}$

The result is 9/10. So it is verify that 81/50 is the value of d.

Answer: 1 31/50

Correct Option: B
