How to calculate it

Method 1: multiply directly

500 × 42% = 500 × 42 ÷ 100 = 21,000 ÷ 100 = 210. 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 500 is 5, so 42% is 5 × 42 = 210. 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: 500 × 42 ÷ 100 = 210. By hand, find 1% first (5) and multiply by 42; the same formula works above 100%, where the result exceeds the base.

Start with 10% (shift the decimal point one place left — 10% of 500 is 50), then combine: 20% is double, 5% is half of that, 15% is 10% plus 5%. Split 42% into 40% plus 2% and add the two parts. With practice, any two-digit base becomes mental math.

Use "part ÷ whole × 100%": 210 ÷ 500 × 100% = 42%. This is the inverse of "find a percentage of a number" — the same relationship, part = whole × percentage, read backwards.

42% = 42 ÷ 100 = 0.42. The percent sign itself means "divide by 100": removing it shifts the decimal two places left, adding it shifts two places right.
