The answer is 1. Below: three ways to calculate it, a mental shortcut, and the real-world contexts where this percentage shows up.
4% of 25 is 1.
4% of 25 — small purchase, small tax.
Divide the percent by 100 to convert it: 4 ÷ 100 = 0.04.
Multiply: 25 × 0.04 = 1.
4% means 4/100. So 4% of 25 is (4 × 25) ÷ 100.
Compute: 4 × 25 = 100, then divide: 100 ÷ 100 = 1.
No single elegant mental shortcut for 4% — but you can always split: 4% = (some 10%) + (some 5%) + (some 1%). Try 0×(10% of 25) plus 4×(1% of 25).
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 $25 purchase with 4% tax, the tax amount is $1 and you pay $26 total.

For any percentage of any number, use our percentage of a number calculator.
Multiply 25 by 0.04 (the decimal form of 4%). Or equivalently, multiply by 4/100. The result is 1.
Divide 1 by 25 and multiply by 100. That is exactly 4% — confirming the original calculation.
The tax is 1, so the total is 26.
