jack and his friends eat a pizza (2). if jack has 4 friends and each friend eats 1/4 peices how much pizza is left?

Answer 1

If Jack has 4 friends and each friend eats 1/4 pieces, then the total number of pieces eaten is 4 friends * 1/4 pieces = <<4*1/4=1>>1 piece.
If the pizza originally had 2 pieces, then the amount of pizza left is 2 pieces - 1 piece = <<2-1=1>>1 piece. Answer: \boxed{1}.
