Convert 0.5 to fraction.

**The reasoning** When you see 0.5, read it as "five-tenths" — literally 5/10. Now simplify by dividing both numerator and denominator by their highest common factor (5): 5/10 = (5÷5)/(10÷5) = **1/2** This is **equivalent fractions** — the value stays the same, just expressed in simplest form. You can verify: 1÷2 = 0.5 ✓ **Why the wrong options tempt you** - **1/4** deceives you if you confuse 0.5 with 0.25 (which *is* 1/4) - **1/3** catches you if you're thinking of 0.333... - **2/3** is actually 0.666..., not even close, but it looks "official" enough to trick a rushed student The trap? Not converting the decimal place value correctly, or forgetting to simplify. **Quick takeaway** 0.5 means "5 out of 10" which simplifies to 1/2 — think of it as splitting something into two equal halves; that's literally what "half" means!
