Answer:
1)
17/20 will have the same value as 1D.
To get this
given D=1
Substitute that into the equation..
you have
E=17/20
To verify this... input E=17/20 into the original equation to see if you will get 1D
17/20 =17/20D
Multiply through by 20/17
You'll have D=1.
So
17/20E will have the same value as 1U.S dollar.
2)
20/17US dollar will Equal 1E.
Solving arithmetically
Given E=1.
Find D subject
your have
D=20E/17
E=1
D=20/17
To verify this answer
substitute D=20/17 and see if you'll get 1E
E=17/20D
E=17/20 x 20/17
E=1.
Conclusion
20/17D will have the same value as 1E
