Express 7/10 as a percentage.

**The reasoning** To convert a fraction to a percentage, multiply by 100%. **7/10 × 100% = 700/10 = 70%** Think of it this way: "percent" means "per hundred" (from Latin *per centum*). You're asking "out of 100 parts, how many?" Since 7/10 means 7 out of 10 parts, scaling up to 100 parts gives you 70 out of 100 — which is 70%. **Why the wrong options tempt you** - **0.7%** — You converted to decimal (0.7) but forgot the ×100 step. A decimal and a percentage are NOT the same thing! - **7%** — You just slapped a % sign on the numerator. That's like saying 7 out of 10 is the same as 7 out of 100 — clearly wrong. - **100%** — That would mean the whole thing (10/10), not 7/10. **Quick takeaway** Fraction → Percentage? **Multiply by 100.** Decimal → Percentage? **Also multiply by 100.** The percentage is always bigger-looking than the decimal because you're scaling to "out of 100."
