Joel cut a pie into an equal number of pieces. He ate 1/3 of the pie. He was left with 8 pieces of the pie. How many pieces did he cut the pie into?
If he ate 1/3 of the pie and 8 pieces are left then 8 pieces = 2/3 of the pie and that means 4 pieces = 1/3 of the pie meaning 12 pieces = 3/3 of the pie so the pie was originally cut into 12 pieces.
Ate 1/3 so 2/3 remains 2/3 x = 8 pieces
x = 8 * 3/2 = 12 pieces originally
