How to calculate it

Method 1: multiply directly

300 × 20% = 300 × 20 ÷ 100 = 6,000 ÷ 100 = 60. 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 300 is 3, so 20% is 3 × 20 = 60. Using 1% as a stepping stone is the fastest mental route when you do not remember the formula.

Method 3: convert to a fraction

20% equals 1/5, so the question becomes "1/5 of 300": 300 × 1/5 = 60. Most everyday percentages map onto simple fractions — memorise the pairs and these answers become instant.

FAQ

The formula is "base × percentage ÷ 100". Plugging in: 300 × 20 ÷ 100 = 60. By hand, find 1% first (3) and multiply by 20; alternatively, treat 20% as 1/5 and simplify.

Start with 10% (shift the decimal point one place left — 10% of 300 is 30), then combine: 20% is double, 5% is half of that, 15% is 10% plus 5%. Here 20% = 1/5, so fraction reduction also works. With practice, any two-digit base becomes mental math.

Use "part ÷ whole × 100%": 60 ÷ 300 × 100% = 20%. This is the inverse of "find a percentage of a number" — the same relationship, part = whole × percentage, read backwards.

20% = 20 ÷ 100 = 0.2, which reduces to the fraction 1/5. The percent sign itself means "divide by 100": removing it shifts the decimal two places left, adding it shifts two places right.
