FAQ

The formula is "base × percentage ÷ 100". Plugging in: 400 × 38 ÷ 100 = 152. By hand, find 1% first (4) and multiply by 38; the same formula works above 100%, where the result exceeds the base.

Start with 10% (shift the decimal point one place left — 10% of 400 is 40), then combine: 20% is double, 5% is half of that, 15% is 10% plus 5%. Split 38% into 30% plus 8% and add the two parts. With practice, any two-digit base becomes mental math.

Use "part ÷ whole × 100%": 152 ÷ 400 × 100% = 38%. This is the inverse of "find a percentage of a number" — the same relationship, part = whole × percentage, read backwards.

38% = 38 ÷ 100 = 0.38. The percent sign itself means "divide by 100": removing it shifts the decimal two places left, adding it shifts two places right.
