How to calculate it

Method 1: multiply directly

500 × 30% = 500 × 30 ÷ 100 = 15,000 ÷ 100 = 150. 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 30% is 5 × 30 = 150. Using 1% as a stepping stone is the fastest mental route when you do not remember the formula.

Method 3: convert to a fraction

30% equals 3/10, so the question becomes "3/10 of 500": 500 × 3/10 = 150. Most everyday percentages map onto simple fractions — memorise the pairs and these answers become instant.

FAQ

The formula is "base × percentage ÷ 100". Plugging in: 500 × 30 ÷ 100 = 150. By hand, find 1% first (5) and multiply by 30; alternatively, treat 30% as 3/10 and simplify.

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%. Here 30% = 3/10, so fraction reduction also works. With practice, any two-digit base becomes mental math.

Use "part ÷ whole × 100%": 150 ÷ 500 × 100% = 30%. This is the inverse of "find a percentage of a number" — the same relationship, part = whole × percentage, read backwards.

30% = 30 ÷ 100 = 0.3, which reduces to the fraction 3/10. The percent sign itself means "divide by 100": removing it shifts the decimal two places left, adding it shifts two places right.
