Here’s the trick that makes you look like a kitchen wizard: To find how many ½ cups are in ¾, divide ¾ by ½. In your head, that’s the same as multiplying ¾ by 2 (because dividing by a fraction flips it). ¾ × 2 = 6/4, which simplifies to 1 ½. See? You just did math that would make Pythagoras weep. No calculator, no panic. Just a casual “Oh, it’s one and a half.”
And if someone challenges you, say, “This is the way of the ancient bakers.” They’ll nod, impressed. They don’t know you just learned it five seconds ago. Now go conquer your measuring cups. One half-cup, and one half of a half-cup, at a time.
P.S. — If you’re still confused, just buy a ¾ cup measuring cup. They exist. They’re cheap. And they will save you from this beautiful, ridiculous mental gymnastics. But where’s the fun in that?
