Money Multipliers

Chapter 27 # 1
Calculate the money multipliers below:
a) Assuming individuals hold no currency, calculate the simple money multiplier for each of the following: 5%, 10%, 20%, 25%, 50%, 75%, 100%.
If individuals hold no cash, the simple money multiplier is the reciprocal of the reserve requirement. Thus for the following reserve requirements the simple multiplier is found by dividing the requirement percentage into 1:
5% - it is 1/5% = 20
10% - it is 1/10% = 10
20% - it is 1/20% = 5
25% - it is 1/25% = 4
50% - it is 1/50% = 2

b) Assuming individuals hold 20 percent of their money in the form of currency, recalculate the approximate real-world money multipliers in a. ( I need help with this one)
