If you’re wondering how many 2/3 cups fit into 1 cup, the answer is simple. You can fit one and a half 2/3 cups into 1 cup. Here’s how:
To calculate, divide 1 cup by 2/3 cup: 1 ÷ (2/3) = 1 × (3/2) = 3/2, or 1.5.
This means that 1 cup contains one full 2/3 cup, plus half of another 2/3 cup (which is 1/3 cup).
So, if you need to measure ingredients and only have a 2/3 cup, just fill it twice, and you’ll have 1 full cup of your ingredient. It’s a simple but handy conversion to keep in mind when cooking or baking!
