These fractions look like a nightmare… until you stop treating all six at once and start pairing them by structure. 22 and 33 both scale to 66. 19 fits perfectly into 38. 13 fits perfectly into 39. Once you see those relationships, you can multiply by a form of 1 — 2/2, 3/3, etc. — to rewrite each fraction with a matching denominator. Because multiplying by 1 never changes value, you get to fix each fraction independently. Suddenly 1/33 becomes 2/66, 3/22 becomes 9/66… and together they collapse

Why can’t you divide by zero? Not for the reason most people think. Division asks: how many copies of the divisor sum to the dividend? When we say 10÷2=5, we mean two groups of 5 add back to 10. For 1÷0, we’re asking: how many zeros add to 1? Add zero plus zero, you’re still at zero. Add infinitely many more, and you never reach anything other than zero. No value satisfies the basic definition. That’s why 1÷0 is undefined. The meaning of division fails to produce a consistent answer. Here’s the
