Let's assume you mean 2/3 cup. That is, two-thirds of a cup. The answers to this one are literally infinite, but could include: One third of a cup and one third of a cup. Also written as: 1/3 cup + 1/3 cup. Or maybe 3/6 cup and 1/6 of a cup. I could go on, but it's not as much fun as I had imagined. I mean, you can just keep multiplying the denominator by some number and coming up with smaller fractions...
