How to calculate it

Method 1: multiply directly

300 × 28% = 300 × 28 ÷ 100 = 8,400 ÷ 100 = 84. 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

FAQ

The formula is "base × percentage ÷ 100". Plugging in: 300 × 28 ÷ 100 = 84. By hand, find 1% first (3) and multiply by 28; the same formula works above 100%, where the result exceeds the base.

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%. Split 28% into 20% plus 8% and add the two parts. With practice, any two-digit base becomes mental math.

Use "part ÷ whole × 100%": 84 ÷ 300 × 100% = 28%. This is the inverse of "find a percentage of a number" — the same relationship, part = whole × percentage, read backwards.

28% = 28 ÷ 100 = 0.28. The percent sign itself means "divide by 100": removing it shifts the decimal two places left, adding it shifts two places right.
