The answer is 1.5. Below: three ways to calculate it, a mental shortcut, and the real-world contexts where this percentage shows up.
3% of 50 is 1.5.
3% of 50 — a small but real tax-rate calculation.
Divide the percent by 100 to convert it: 3 ÷ 100 = 0.03.
Multiply: 50 × 0.03 = 1.5.
3% means 3/100. So 3% of 50 is (3 × 50) ÷ 100.
Compute: 3 × 50 = 150, then divide: 150 ÷ 100 = 1.5.
No single elegant mental shortcut for 3% — but you can always split: 3% = (some 10%) + (some 5%) + (some 1%). Try 0×(10% of 50) plus 3×(1% of 50).
Sales tax is a percentage added to a purchase. To find the total, calculate the tax first, then add it to the price.
On a $50 purchase with 3% tax, the tax amount is $1.5 and you pay $51.5 total.

For any percentage of any number, use our percentage of a number calculator.
Multiply 50 by 0.03 (the decimal form of 3%). Or equivalently, multiply by 3/100. The result is 1.5.
Divide 1.5 by 50 and multiply by 100. That is exactly 3% — confirming the original calculation.
The tax is 1.5, so the total is 51.5.
