Question

You have a pie. The pie is divided into five equal pieces. Each piece is eleven cubic cm in volume. Your brother eats one piece. Each of the remaining pieces is divided in half again. Is the remaining volume of pie greater, less than, or equal to a third of the original volume?

Answer 1

5 x 11 cm^3 = 55 cm^3 pi3

your brother eats one piece, of 11 cm^3 leaving 44 cm^3

the remaining 4 pieces are cut in half, with the 11 cm^3 pieces now 8 pieces of 5.5 cm^3 each

1/3 of the initial volume = 55/3 = 18 1/3 cm^3 < 44/2 = 22 cm^3

1/3 of the initial volume is less than what's left after your brother ate one piece and even after half of what's left isn't counted.

the problem appears a little ambiguous as to what you're comparing, but however you do it, that 1/3 seems less than whatever is left.
