Did you know the fraction 2/3 is an ancient superstar? The Egyptians used it as a unit fraction (1/3 + 1/3). They had a special symbol for it because 2/3 is the only fraction with an even numerator they found sacred. Quirky, right?
In recipes, 2/3 appears so often that some cultures have dedicated measuring cups for it. The Japanese have a “2/3 cup” for tea ceremonies. The French use it for crêpe batter. It’s a global citizen of measurements.
And here’s a laugh: In 2026, a viral TikTok asked “What’s 2/3 of 2 1/2?” Over 2 million people watched before someone answered. It became a meme. Math goes viral when it’s about food.
