Donna is catering for a party. She makes 20 sandwiches and then cuts them in half, before cutting them in half again. She then gives everyone 8 portions. How many people can she feed?
First, we need to determine the overall number of portions. To do this, we begin by performing 20*2= <T>multiply(20, 2)=40 portions after the first halving.
Next, we take this portion number and double it again, performing 40*2=<T>multiply(40, 2)=80 portions after the second halving.
Lastly, we divide this portion number by the number of portions each person will be served, performing 80/8=<T>divide(80, 8)=10.0 people served.
