I don't know if this is a mistake, because you are still asking for 0.5% of 60 due to where you put the decimal point. If this is deliberate, then to find 0.5% of 60 you divide by 10 to find 10% (6), and then divide by 2 to find 5% (3). You can then just divide this by 10 to find 0.5%, which would be 0.3. If this is not deliberate, then you'd get 5% (3) and divide by 10,000,000, which just gets you to 0.00000003. I hope this helps!
