Three ways to calculate 4% of 25

Method 1: convert 4% to a decimal

Divide the percent by 100 to convert it: 4 ÷ 100 = 0.04.

Multiply: 25 × 0.04 = 1.

Method 2: use the fraction form

4% means 4/100. So 4% of 25 is (4 × 25) ÷ 100.

Compute: 4 × 25 = 100, then divide: 100 ÷ 100 = 1.

Method 3: mental shortcut

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).

Why this calculation matters
