You can put this solution on YOUR website! This is very similar to This Question, but in case it's not a duplicate, let's go ahead and work it.
.
To do this type of problem, we work backward.
At the end, Gloria has 9 pieces left. She gave friend 2 half; therefore, she gave him 9 pieces.
Before meeting friend 2, Gloria had 18 pieces. She gave friend 1 half; therefore, she gave her 18 pieces.
18 + 18 = 36 pieces to start with.
