Here’s the rub: 2/3 cup is a weird fraction. It’s bigger than half a cup but smaller than a full cup, so it never lines up perfectly with whole numbers. That’s why you end up with that “point five” at the end.
Think of it this way: three 2/3 cups actually make 2 cups (because 3 x 2/3 = 6/3 = 2). So you’re already two-thirds of the way to 3 cups. You just need one more 2/3 cup—and then half of another one to finish the job.
It’s like trying to fit square pegs into round holes, except the pegs are flour and the hole is your mixing bowl. Fun, right?

How to Actually Measure This Without Losing Your Mind
Okay, so you need 4.5 scoops. Here’s the practical way to handle it. Grab your 2/3 cup measure and scoop four full times. Dump each one into your bowl.
Now you have 2 and 2/3 cups in the bowl (because 4 x 2/3 = 8/3, which is 2 and 2/3). You’re close, but not at 3 cups yet. You need that last 1/3 cup.
To get that half scoop: fill your 2/3 cup measure halfway. Or, if you’re lazy (like me), just use a 1/3 cup measure for the last push. Two of those equal 2/3, so one equals 1/3. Done. You’re a genius.
