Paula and Jack bought equal-sized bottles of juice. Paula drank 1/8 of her bottle. Jack drank 5/8 of his bottle. How much more juice does Paula have left than Jack? Find the difference
Paula drank 1/8 of her bottle, so she has 1 - 1/8 = 7/8 of her bottle remaining.
Jack drank 5/8 of his bottle, so he has 1 - 5/8 = 3/8 of his bottle remaining.
Paula has 7/8 - 3/8 = <<7/8-3/8=1/2>>1/2 more juice left than Jack. Answer: \boxed{1/2}.
