How to calculate it

Method 1: multiply directly

1,000 × 10% = 1,000 × 10 ÷ 100 = 10,000 ÷ 100 = 100. 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 1,000 is 10, so 10% is 10 × 10 = 100. Using 1% as a stepping stone is the fastest mental route when you do not remember the formula.

Method 3: convert to a fraction

10% equals 1/10, so the question becomes "1/10 of 1,000": 1,000 × 1/10 = 100. Most everyday percentages map onto simple fractions — memorise the pairs and these answers become instant.

FAQ

The formula is "base × percentage ÷ 100". Plugging in: 1,000 × 10 ÷ 100 = 100. By hand, find 1% first (10) and multiply by 10; alternatively, treat 10% as 1/10 and simplify.

Start with 10% (shift the decimal point one place left — 10% of 1,000 is 100), then combine: 20% is double, 5% is half of that, 15% is 10% plus 5%. Here 10% = 1/10, so fraction reduction also works. With practice, any two-digit base becomes mental math.

Use "part ÷ whole × 100%": 100 ÷ 1,000 × 100% = 10%. This is the inverse of "find a percentage of a number" — the same relationship, part = whole × percentage, read backwards.

10% = 10 ÷ 100 = 0.1, which reduces to the fraction 1/10. The percent sign itself means "divide by 100": removing it shifts the decimal two places left, adding it shifts two places right.
