​ DE, equals, start fraction, 17, divided by, 20, end fraction, D.

Answer 1

1 dollar is equivalen to 85 cents of an euro.

Explanation:

The given expression is

`E=(17)/(20)D`

Where
`E` is euros and
`D` is dollars.

Using this expression we can calculate the amount of euros equivalent to one dollar:

`E=(17)/(20)(1)=0.85`

Therefore, 1 dollar is equivalen to 85 cents of an euro.

Answer 2

0.85 Euros have the same amount as 1 U.S dollar.

Explanation:

Given : The equation
`E= (17)/(20)D`

To find : Number of Euros which has same value as D U.S. dollar ?

Solution :

The equation
`E= (17)/(20)D`

Where, E= amount of Euros

D= amount of U.S dollar.

Now for 1 U.S dollar we put D=1,

`E= (17)/(20)(1)`

`E= (17)/(20)`

`E= 0.85`

Therefore, 0.85 Euros have the same amount as 1 U.S dollar.
