How to calculate it

Method 1: multiply directly

50 × 18% = 50 × 18 ÷ 100 = 900 ÷ 100 = 9. A percentage literally means "per hundred", so multiplying the base by the percentage and dividing by 100 gives the part.

Method 2: find 1% first, then scale

1% of 50 is 0.5, so 18% is 0.5 × 18 = 9. Using 1% as a stepping stone is the fastest mental route when you do not remember the formula.

FAQ

The formula is "base × percentage ÷ 100". Plugging in: 50 × 18 ÷ 100 = 9. By hand, find 1% first (0.5) and multiply by 18; the same formula works above 100%, where the result exceeds the base.

Start with 10% (shift the decimal point one place left — 10% of 50 is 5), then combine: 20% is double, 5% is half of that, 15% is 10% plus 5%. Split 18% into 10% plus 8% and add the two parts. With practice, any two-digit base becomes mental math.

Use "part ÷ whole × 100%": 9 ÷ 50 × 100% = 18%. This is the inverse of "find a percentage of a number" — the same relationship, part = whole × percentage, read backwards.

18% = 18 ÷ 100 = 0.18. The percent sign itself means "divide by 100": removing it shifts the decimal two places left, adding it shifts two places right.
