The answer

3% of 50 is 1.5.

3% of 50 — a small but real tax-rate calculation.

Three ways to calculate 3% of 50

Method 1: convert 3% to a decimal

Divide the percent by 100 to convert it: 3 ÷ 100 = 0.03.

Multiply: 50 × 0.03 = 1.5.

Method 2: use the fraction form

3% means 3/100. So 3% of 50 is (3 × 50) ÷ 100.

Compute: 3 × 50 = 150, then divide: 150 ÷ 100 = 1.5.

Method 3: mental shortcut

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).
