Answer 1

Bethany says, Using these exchange rates, £1 is worth 1.17 euros.

Explanation

1 euro = 1.07 dollars

£1 = 1.25 dollars

Now ,

⇒ £1 = 1.25 dollars

⇒ £1 =
`1.25dollars((1.07)/(1.07))`

⇒ £1 =
`(1.07dollars)((1.25)/(1.07))`

⇒ £1 =
`(1euro)((1.25)/(1.07))`

⇒ £1 =
`(1euro)(1.17)`

⇒ £1 =1.17 euros

Therefore , Bethany says, Using these exchange rates, £1 is worth 1.17 euros.
