Choose the numbers that are irrational.
ddd [48]
As the numbers are written, none of them are irrational because they are all terminating decimals:

3.624=\dfrac{3624}{1000}=\dfrac{453}{125}
0.6=\dfrac6{10}=\dfrac35
0.87=\dfrac{87}{100}
-5=-\dfrac51

Perhaps there is some missing notation in your question?
