Question

if the foreign exchange rate between U.S dollar and danish krone is 1:2.50 how many danish krones will you get for $5

Answer 1

`12.5` Danish Krones

Explanation:

The ratio of US dollars to Danish Krone is

`1:2.50`

Let
`x` Danish krones give $5.

Then we can again write the ratio,

`5:x`

The proportion is

`5:x=1:2.50`

We rewrite the ratios as fractions to obtain,

`(5)/(x)=(1)/(2.5)`

We cross multiply to get,

`2.5 * 5=x`

This implies that,

`12.5=x`

Therefore
`12.5` Danish Krones will get you $5
