In 2012, 1 danish krona cost.59 israeli shekels and in 2015 it cost.53 israeli shekels.
how much would 1 israeli shekel purchase in danish krona in 2012 and 2015?
o 2012: 1.78 shekels, 2015: 1.98 shekels
o 2012: 1.69 shekels, 2015: 1.89 shekels
o 2012: 1.71 shekels, 2015: 2.00 shekels
o 2012: 1.73 shekels, 2015: 1.97 shekels

The answer is:

2012: 1.69 shekels,

2015: 1.89 shekels

Explanation:

The correct way to solve this is to find the mutual relation of these two currencies. We already know that:

-in 2012 1 Danish krona (DK) equaled to 0.59 Israeli shekels (IS)

-in 2015 1 Danish krona equaled to 0.53 Israeli shekels

Now we want to know how much would 1 shekel purchase in kronas. Let's make the proportion. For 2012:

1DK : 0.59IS = xDK : 1IS

So, x is 1/0.59=1.69DK

For 2015:

1DK : 0.53IS = xDK : 1IS

Similarly, x=1/0.53=1.89DK

So, the right answer is 2012: 1.69 shekels, 2015: 1.89 shekels
