Once. You subtract 5 from 25 getting the result of 20. You could subtract 5 from 20 next but not from 25. My answer is a trick answer. You can remove 5 pennies from a pot of 25 pennies a total of five times until there are no pennies left in the pot, You can subtract 5 from a prior number an infinite number of times. So that is also a trick answer. What was the original question's intent?
