Mindy and Troy combined ate 9 pieces of the wedding cake. Mindy ate 3 pieces of cake and Troy had 1/4 of the total cake.. Write an equation to determine how many pieces of cake (c) there were in total.
9-3=6
Troy ate 6 pieces of the cake
1/4 of the cake equal 6 pieces of the cake
There are 6x4=24 pieces of the cake in total.
